Lakshya NEET in English 2027 Batch🚨 Chemistry First Class FREE | Don’t Miss

Added: 2026-05-05

[00:00:09]Hello students. So welcome to first class of our Laksh neat 2027 English batch. So I'm very much super excited to see each and every one of you in this particular batch. The main thing why I'm that much happy means from day one. So from today onwards each and every one of your life is going to change. So this is the very very important crucial step also what we are taking in our life. I believe yesterday the first class of our Lakshmi 2027 English batch physics has been completed. Right. Sir completely discussed everything. I also personally came to know sir given certain promises.

[00:00:57]In the same way as a student each and every one of you given the promise. Am I right? Yes. So very good evening. Very good evening. Good evening my dear students. Yes. So when it comes to chemistry so before getting into the session directly one thing I want to make very very clear for the students. Please do keep this in mind till now due to any reason it might be anything due to any reason if you guys didn't enroll in our batch means so now at least don't delay further so since the first class will be the free class I am just coming live in YouTube from tomorrow onwards where exactly I'm starting here where exactly ly I'm starting the class where I'm going to stop from there only once again I will continue so the second class onwards will be only 100% will I will be coming in live only in our application so please take it very seriously due to any reason some students may require some time actually to pay the fees whatever let it be my dear students but please don't miss the class because now classes has been started each and every live class is very very important. If you people talk to your seniors, what is the thing? Sir, it is possible to crack neat in last 60 days. Sir, it is possible if I listen only one shot, I can able to clear the lecture. Yes, obviously I am the one taking one shots in YT also, right? Yes, everybody can able to clear the exam. In chemistry out of 180, everybody can easily able to score 130 to 140. If you people attempt all my one short lecture, all the strategies whatever but tell me one thing my dear students is there any guarantee for us in need 2027 chemistry paper will be easy. Is there any guarantee for us? No guarantee in need 2025 we got one of the toughest paper in physics. Let it be whatever. I will never blame the question paper setter.

[00:03:15]If we are keeping our preparation to this level whoever the question paper set whatever the question we can able to solve but that confidence that attitude we will get only from day one of our preparation only if we prepare from day one of the class if you guys travel with me for the next 365 days each and every one of you can able to crack exam that too I'm 200% sure I can write and then I can give also if you people listen the classes carefully whatever the notes I'm going to give whatever the homeworks I'm giving please do follow it you guys can able to really score 180 out of 180 even if the question paper comes tough for other students it might be a difficult question but for you people it will be like hey Pritis asked this question in class no pris given this question in DPP homework no yes my dear students now before getting into the first as the one of the very important thing strategy.

[00:04:19]See things will never come in one night my dear students we need to do hard work but more than hard work consistency is important I'm not going to tell you guys need to study for next daily 12 hours you guys need to study chemistry no one need to study daily 12 hours of chemistry everybody getting an idea yes no need to study 12 hours daily what is the commitment I'm just going to ask from each one of you Daily if you people revise whatever I am going to teach whatever the homework I'm going to do I'm going to give just do that only whatever the class notes I'm going to give whatever the homework I'm going to give do only that to 200%.

[00:05:07]automatically without any excuses. Next day I don't want you people to tell me excuses. So without excuses whatever the things I'm just going to do in class follow that definitely you guys can able to crack. I will take 100% responsibility because any number of my previous students are there currently in GMC Jimmar as buberneshwar all those things. So how those students entered in the same way I'm very happy even I'm getting more confident some of my previous students scored the all India rank of 200 or 300 plus but I believe from this batch need 2027 exam when it is going to happen I am getting the inner feel that definitely from our batch majority of the students can able to score all India rank of between 1 to 100. Yes, it is possible my dear students, it is possible. But what is the thing we need to do? Dedication and then consistency. Discipline. Discipline is required. Daily 2 hours I will read daily night 10 to 12 I will read chemistry means even if the sky comes to earth we need to do it. So discipline is very very important. If we are not having that sort of discipline then it will be really tough. When it comes to majority of the students even I'm telling from my personal experience what is the usual thing will be happening means now 11th has been completed already in 11th actually we will be having so much trauma organic chemistry organic chemistry tell me honestly for how many of you still organic chemistry is the nightmare tell me honestly my dear students see uh before discussing everything strategy about chemistry first I want to tell about myself see this Next one year I'm just going to travel with you guys. I'm going to make each and one of you be a top ranker in neat examination. Myself Prits I will be handling all three parts of chemistry. I will be handling all three parts of chemistry inorganic, organic as well as physical. So if you guys want to know about me first that is also very important because in our class it is like a offline class only. My dear students, you guys can ask me anything through chem through through your chat.

[00:07:27]Definitely I will be answering each and every one of your answer. I will be clarifying your doubt as always my colleague Subra sir my friend he will be always telling yes we will be pinpoint teaching the concept but still we will be a personal mentor. We will be sharing our life experience how I cracked when it comes to toughest examination. how I approached the chemistry, why on what basis, how I mastered the chemistry that to all three parts of organic chemistry, everything one by one you people will come to know automatically. Yes, I am ready for this learning process. First thing throw off one thing from your mind. Hey Priti sir, yes sir is very good in chemistry. He will be rocking all three parts of chemistry. I don't want all those thoughts.

[00:08:12]Team me like a friend. I am just going to travel with you guys for the next one academic year even I don't know what is solution even I don't know what is electrochemistry but still in that perspective you guys need to think as a friend try to learn the things from me in the same way whatever the doubts don't hesitate see in our class you guys can can able to do mistake do mistakes no problem tell me the wrong answers because of small small confusion if you lack basics also it is fine my dear students I'm not going to scold you guys what is our target my students can do mistake in front of me but in our final neat examination when it comes to neat 2027 I don't want my students to do silly mistakes in the exam yes to the outside world each and every one of you should be a topper but in our class now only you people going to learn the things in a proper way so I will be definitely supporting trust me if you have any doubt okay prat sir do really teach well honestly ly I'm telling you guys can see any of my YT lecture so automatically you guys will understand whatever the things I will exactly start from the scratch my dear students it is clear yes siri sir which chapter you are going to start yes exactly we will discuss all those things so before that since this is the first class I will be telling the complete strategy followed by the very first chapter in 12th class that is solutions ions I'm going to start the very first chapter solutions once again I'm telling first class so it will be free you guys can able to see me in YT also but remember not that is what I'm telling dashan sir will we have live on YouTube that is what I'm telling today only you people are getting live in YT tomorrow onwards my class will not be coming in YT so please don't lose the opportunity don't think sir will be taking one shot anyhow after December that is enough for me. No my dear students so the first priority is regular classes the regular students whoever enrolled in my batch so please don't delay further without any hesitation enroll because you people got experts for this neat 2027 examination yes more than me when it comes to physics yes subrats he is a very hardworking strategical person person in approach next the biology legend we are having botanian ology both will be handled by Ambika ma'am single teacher is going to handle both the subject so you people can ask any doubts you people can master both bot as well as dology 360 out of 360 50% is complete it's already decided yes with the help of ma'am you guys can able to master that those subjects like ma'am said so please do keep all these things in mind when it comes to first thing my dear students when it comes to first thing today class before getting into today class I want to tell certain things there are a way to approach chemistry from day one onwards because chemistry is not a easy subject what sir you are telling like that usually everyone will tell chemistry even my seniors told even the past seniors whoever completed neat examination they told yes chemistry is easy even now J exam has been completed J 2026 both the shift chemistry is easy in the same way neat 2026 also chemistry will be easy but why I'm telling it as tough first subject We need to approach in a proper way then only subject will be easy otherwise it will be very very yes basha yes exactly I'm just going to take all three parts of chemistry organic inorganic as well as physical it is clear so how sir will handle all these three things if you people want to know about me yes I also started my journey like you people without knowing anything in chemistry zero in chemistry but after my 12th class I did my engineer engineering.

[00:12:13]After that I cracked examination. Then I started working as a J mains faculty.

[00:12:18]Then I promoted as a advanced faculty. I was working as a advanced physical chemistry faculty. Then I shifted to other organization. There I started working as a NEAT as well as EAMC faculty. There I produced top ranking NEAT as well as EMC. Then followed by that I was once again I was handed over J batches as well as need batches. Now in the physics world also I'm doing the same thing. So very simple my dear students. So believe your teacher trust me I'm not telling in a normal way. See honestly I'm telling since this is the first class I'm talking this much next class means previous class homework I will ask then immediately I will jump into questions because not only questions concept because from day one we need to teach start preparing exactly from the scratch then only we can able to crack the exam that is very very important. Okay. Yes. Exactly. Exactly.

[00:13:10]Go three. Okay. Now we will get into the session. So before starting only one thing I will be telling to all my students. So please do keep this in mind. This is very very important.

[00:13:23]Today exactly we are starting our class right. What I want what I am expecting from each and every one of you is just anybody can tell me what is CPR in biology. Anyone know? Anybody can tell me what is CPR in biology. My dear students, what is CPR in biology?

[00:13:47]Yes, anybody can tell me. What's the first day? It's a biology class.

[00:13:53]See, everyone want to be a doctor.

[00:13:55]Right. My dear future doctors tell me what is CPR?

[00:13:59]It is some emergency procedure, right?

[00:14:02]If the heartbeat got stopped, doctor will do some emergency procedure. Now what is the thing we need to do with this CPR means? Please do remember one thing my dear students what I want you guys to do with this CPR means first thing please be consistent to the class.

[00:14:23]Consistency is very very important.

[00:14:27]Please be very consistent. Consistences consistency is very very important. Sir 2 days I will attend the live class.

[00:14:34]Third day I will take break. Fourth day sir yes sir prit sir how are you I will be watching your recorded lecture I will tell okay okay my dear yes we will watch the recorded lecture no please be consistent in attending the class don't miss any live classes okay I just need your presence for all live classes because why means when I am increasing the level of the subjects solution chapter I will start from the scratch slowly third class fourth class I will be touching the advanc concept. I will be telling that time this is only for advance like that I will tell but remember one thing those time you people will get any number of doubts if you people are in live class anyhow I will be meeting you guys in doubt session all those things but still in live class along with the students when we are solving the doubt that is different everybody getting the point even suddenly now when you people are listening the class suddenly one doubt will pop into our mind but the same doubt no will not be there in our mind even we will we won't even remember sometime. So please do keep this in mind. Okay. Now consistency is very very important. After that class notes stick to my class notes sir. Why I need to stick to your class? I will prepare on my own. I will tell one thing my dear students understand one thing first.

[00:15:58]When it comes to books books are very very important. Even though NCERTT is a base for neat examination, reading NCERTT alone is not sufficient.

[00:16:15]First thing keep in mind, keep in mind as my students, reading NCERTT alone is not at all sufficient. So what you guys need to do? Not only NCERTT when it comes to different branch of chemistry remember one thing we will be having organic chemistry in the same way we will be having physical chemistry then in the same way we will be having inorganic chemistry.

[00:16:48]Now there are certain standard book each and every one of you need to study line by line reading understanding the concepts everything is important. Very few books I will tell if I talk about organic chemistry definitely each and every one of you need to do Yamas Chauan in organic chemistry. Yamas Chawan for J advanc organic chemistry as well as J means as well as ne theory textbook. We need to solve questions from Yas Chawan.

[00:17:20]Not only Yamas Chawan, we need to solve questions from Himman Shu Pande.

[00:17:28]In the same way when it comes to physical chemistry definitely everyone need to do questions from Kapour physical chemistry by Kapoor. Apart from that for theory perspective we need to study physical chemistry by Atkins or else Purian Sharma all these textbooks are very very important when it comes to inorganic chemistry we need to remember the trends everything right. So for inorganic chemistry also we need to refer for inorganic chemistry all trends exceptions everything is very very important right. So for inorganic chemistry we need to study JD.

[00:18:12]Yes. Apart from that so many textbooks are there like this any number of textbooks are there. My dear students apart from this as a student what you guys need to do when it comes to physical as well as organic one textbook will be there. What is that? OP tand this also you guys need to study. Now tell me as the student if I tell you guys to score 700 plus mark in neat examination you guys need to solve question from Yamas Johan and Iman Shuanti you guys need to read theory from Puran Sharma you guys need to solve questions from opinion in the same way for inorganic chemistry. If I tell all these things tell me honestly it is possible for us to read all this textbook as a student along with physics along with boty along with zoologology regular classes will be there class notes DPP all the works will be there it is possible my dear students it is not at all possible I'm telling the truth you parents listening to my class also please don't force your child to read all this textbook hey sir told I will purchase all this textbook go read then only you can able to score 700 plus. My dear students, my existing students know, even my previous students know very well, you people also will realize my class notes is more than sufficient.

[00:19:33]My class notes is more than sufficient.

[00:19:37]Everybody getting the idea? Whenever I'm teaching the concept in my class notes, it is my personal promise. My dear students, I will be starting from the scratch NCERTT. Apart from that, I will be discussing case based question, fact based question.

[00:19:57]Along with this, I will be doing PYQS.

[00:20:03]In the same way, I will be using JWE questions for some concepts. Even I know the question paper mindset, right? These many years I was producing rank even I know question paper said that I wantedly frame some of the J advanced PYQ questions in the exam what concept and all they will touch that number of stereo isomers number of optical isomer number of geometrical isomers otherwise RLVP related problems all these you people know optical isome stereo isomeism everything because you people would have studied in 11th class but when it comes to this particular solution chapter also when it comes to RLVP P if they want to frame a very tough paper, if they want to bring down the rank of all the students, then wantedly they will frame RLVP, relative lowering of paper pressure questions from advance. This is what happening. So you guys no need to worry about all these things. What in my class I will be discussing everything my class notes if you ask sir which textbook you are referring these are all my reference my dear students. These are all my reference. These are all my reference textbook. Whatever the content I'm teaching, you guys can able to see that in NCERTT. Whatever the exception I'm teaching, you guys can able to see in single class. I will tell my dear students, zinc amalgam is an exception.

[00:21:26]Whatever the liquid solid, I will be telling. But you guys can I will be writing some 10 example. You guys can able to see two two example from all the textbook. So what I will be doing I'm not going to sit and read now already 10 years I'm referring all this textbook now everything is there here so don't worry my dear students other than my class notes and then NCERTT textbook no need of any other textbook no need of any other textbook our PW module you people can use to solve question I believe when you people are purchasing the course purchasing the course everyone will be having PW module with you right how many of you is having PW PW module please do tell me please do let me know my dear students how many of you are having PW module yes is everybody is having so when it comes to homework questions also what I will be doing means I will be giving the question number from our PW module it is clear I will be telling yes the class is done and rested in our module question number 49 question number 71 is the homework like that I will give so please do purchase module also that also will be very very important content it is clear everybody getting the clearcut idea now so class notes that is very important okay sir how you will be doing in class concept question concept question that will be the way I will be teaching the entire concept even after in today class you people will observe right how I'm teaching concept question concept question so end of the class definitely homework will be there apart from that DPP also will be there what is DPP daily practice problem I will be getting giving minimum 15 to 20 question from whatever the topic we are discussing in the class not from entire chapter after every lecture you people will be having DPP that will be the homework all details you people will be getting in the application next class notes when it comes to class notes concept plus question after that you people will be having DPP now what is P is nothing but practice P is nothing but practice What practice we need to do?

[00:23:36]What practice we need to do?

[00:23:39]DPPP question. I'm giving the homework, right?

[00:23:43]DPP question you guys need to practice.

[00:23:46]Other than that, whatever the question I'm giving, so whatever the questions I'm discussing in the class, whatever the PQs that you guys need to practice otherwise DPP or else module I will include. Yes, you guys can solve the question which is there in our module.

[00:24:05]Then what is R? That is very very important revision.

[00:24:11]Last R stands for revision.

[00:24:17]So what we need to revise class notes plus NC.

[00:24:27]So my dear students if we follow this three things CPR automatically you guys can able to score marks. It is clear automatically you guys can able to score marks. So it is very simple follow these things remaining everything personally I will take care nothing to worry whatever the concern you people are having. Yes, you guys can tell me since this is the first class I'm giving all these advices everything in the future classes also I will be giving advice but not for this long even I hate giving advice even I hate taking advice also so please be true to yourself that's it because when dad or mom is questioning us hey are you studying seriously how is the classes going are you listening everything carefully we should not tell lie my dear students Please be very honest in life. That is very very important. So please be true to yourself. In the same way do the hard work. Definitely you guys can able to score marks. No one can stop you guys.

[00:25:34]No one can able to stop you guys and from entering into the government medical college. Definitely you guys can enter. It is clear. It is done. Anybody still having any concern?

[00:25:46]Yes. So when it comes to this particular batch lakshit 2027 12th board as well as neat examination.

[00:25:56]So in 11th class if you people are having any problem I know actually why I'm not touching that part means even daily I'm actually with students only I know very well about my students right all the students I know whoever completed their 11th no they are having problem with organic chemistry some students are having problem with physical chemistry that two mainly thermodynamics part some students are having problem with ionic equilibrium buffer solution hydraulysis some students are having problem with chemical ical bonding not in hybridization when it comes to exception in hybridization when it comes to hydrogen bond questions they will ask which one of the following hydrogen bond is strongest their problem will be there sir I know definition everything but I can't able to solve the question what I need to do yes sir will you thought 11th class that is what yes exactly because now tell me now I'm going to start hello without organic basics it is possible for me to teach. I need to check right whether you guys know the basics or not.

[00:27:01]So I will be including all those things also in my current lecture. So don't worry my dear students. It is clear.

[00:27:08]Don't worry. Yes, you guys can able to crack it is clear. So yes yes Lima now I'm starting the class. Fine. No doubts right? Okay. Just do follow the lecture.

[00:27:20]That is very very important. anything anywhere you people are facing difficulty immediately stop me and let me know definitely I will do it and then very sorry for consuming nearly half an hour so follow this CPR technique whenever if anyone ask you are you preparing for need CPR technique should come in mind as simple as that C for not chemistry sir C for consistency are you listening the class regularly are you attending the class regularly class notes are you following P practice are you doing revision so if you people are doing these three things automatically we can able to achieve it is clear so don't worry about the exam pressure I know how to make you guys to score out of out in chemistry chemistry is my responsibility my dear students so please don't worry I'm here for you guys I will be putting my 200% effort I will be putting 200% effort I will be putting so when it comes to each and every concept I will be starting from the scratch I will be pitching to the Mains level, advanc level also I will be telling you people honestly this is only for advanc. I'm just telling you guys because if need paper comes stuff means this concept is required like that I will be telling in all my classes don't worry.

[00:28:33]Yes. So once again I'm reminding this will be the last YT lecture of Lakshi 2027 batch in YT you people can't able to see my further lecture please do enroll in batch. Sir should we make notes during class? No my dear students split listen solve question anyhow after the class you will be getting all my notes why to sit and do why to take the notes I will be giving some important question I will be giving 30 seconds time you will tell sir I was copying previous page sir very sorry I don't want all those things so my dear students put 100% attention in my class I will be giving question also that is the thing I am the person I won't see like yeah this is need students this is J students no I will be push hitting you people hard with the concepts. Yes, exactly my dear students because a number of my students will always tell sir uh when we are seeing the question paper we are hearing your voice majority of my students told me this so please do keep this in mind don't worry I'm there when it comes to chemistry you people won't face any difficulty fine okay so I will be starting now yes exactly harsha what about when it comes to once again I'm telling board syllabus solutions when it comes to board that is The first chapter we are going to prepare for board as well as neat that is also my responsibility.

[00:29:54]Yes. Yes. Exactly. Lux batches especially for board plus need. Once again I'm telling our lux batches especially for board plus neat. I will be giving 200%. I will make each and every one of you to score full marks in board as well as in neat examination also.

[00:30:14]Right? So don't worry don't worry. I will be teaching for both the stuffs.

[00:30:20]Yes. Okay. It is clear. No. If you are having physics wall app itself, you can't able to see the class. You guys need to enroll by paying the required amount of fees. It is very less my dear students. Personally, shall I tell it is a year fees because personally if you go somewhere offline classes no you guys know very well more than me. You guys know very well about outside what is happening. If you people talk with your friends or relative. So it is for entire 1 year. So please do purchase. Don't uh what to say? Uh don't lose the opportunity. That's it.

[00:30:55]Okay. Schedule everything you people will be getting in announcement section of the app. Schedule everything you people will be getting in announcement section of app.

[00:31:07]Okay. In laptop also you can do. Yes.

[00:31:11]Okay. So let me get into the class now.

[00:31:14]First thing as I told we are going to start with solution chapter let me start the chapter the same thing whether it is inorganic organic physical concept followed by question I will be discussing everything in detail even though if you people don't know anything even what is mole also I don't know sir how I will be doing don't worry you people trust me right that is my responsibility you guys will become mastering chemistry like me my responsibility I will be teaching everything yes as I Sir, are you giving DPP today? Yes, already I given to the back end team. You people will receive the DPP. What you guys need to do after the class? Revise my notes and then start solving question. It is clear.

[00:31:54]Everyone is ready. Is everyone is ready?

[00:31:58]Right? Clear. Now, shall we start the session? Yes. Shall we start the session? Perfect. Now, first thing when it comes to solution, what we need to learn?

[00:32:12]Yes. what we need to learn when it comes to this particular topic solutions listen carefully all the points I'm going to write because in neat examination line by line textbook reading is very important if you people read my class notes that is more than sufficient no need of textbook that also I will tell honestly okay yes really they're so excited yes listen carefully questions you guys need to solve in class will be definitely questions will be there concept question. Okay. Yes.

[00:32:47]When it comes to solution what is the first thing what we can able to tell?

[00:32:52]One thing I will tell when it comes to solution chapter not only solution solution plus redux plus electrochemistry.

[00:33:02]These three chapters are interrelated.

[00:33:06]Please do keep this in mind. Solution redux electrochemistry. All these three things are interrelated. How? In redox in 11th class we will be talking about electron. Your teacher would have taught you guys right? Number of electron transfer valency factor. So based on that we will be doing this electrochemistry. Okay sir how the solution chapter is related.

[00:33:30]You guys know very well in 11th class when you people are doing this redux reaction we will be getting sure short questions based on this 0.5 molar solution is titrated against KMO4 am I right or not we will be getting those sort of question to solve those sort of question what is very important solution chapter is very very important solution chapter is very very important now first thing if someone ask You what is solution? How we can able to tell?

[00:34:03]Basically solutions are homogeneous mixture.

[00:34:09]That is the first point very important.

[00:34:12]So don't have bias in your mind. Sir this and all won't come. This and all very easy in chemistry only this tough question will come. Sir from day one my student should have any prediction because we can't able to predict the question paper set. anything you may he or she may ask in the exam. So please be very careful. Yes. Homogeneous mixture solutions are basically homogeneous mixture. It contains how many component?

[00:34:38]Homogeneous mixture of more than one component. Homogeneous mixture of more than one component.

[00:34:50]Now one question will come one thing understand when it comes to its characteristic property this is fine solutions are homogeneous substance it contains more than one component. Now this homogeneous mixture right this will have unique characteristics in the mixture. This homogeneous mixture will have unique characteristics in what?

[00:35:21]In the mixture. This homogeneous solution will have unique character in the mixture. I will tell everything. First thing when it comes to types of solution when it comes to types of solution what are the types we will be having sir what sir what are the types listen carefully basically solution is the homogeneous mixture it has more than one component it will be having unique characteristics that is fine when it comes to type of solution remember one thing on what basis I'm going to classify This means on the basis of components on the basis of component on the basis of component how it is possible for me to classify I will be having three different types of solution. One is called as binary solution.

[00:36:27]Next one is called as any idea? Yes. Any idea? Turnary solution.

[00:36:36]One thing is called as binary solution.

[00:36:38]The second one is called as turnary solution. The last one is called as quartinary solution. The last one is called as quartinary solution. Sir, what is binary solution? Turnary solution.

[00:36:54]Very simple my dear students. Now understand.

[00:36:58]Now let me take this in my hand. What exactly I'm having in my hand? Yes sir.

[00:37:05]What is that liquid inside? It is just water only.

[00:37:09]Okay, you guys know very well, right? So see that is what my chemistry class. So I will be teaching everything in detail.

[00:37:16]So my dear students, any of you due to any reason couldn't able to enroll or due to any reason personal reason delay is happening. So please don't miss the opportunity from tomorrow onwards class will be coming only in application. Now listen carefully this is water right now in this container I'm having only water.

[00:37:33]Now what I'm going to do is I'm just going to this water in the beaker I'm having only water. Am I right? Yes. Only water component I'm having. Now what I'm going to do means I'm just going to add sugar in this water.

[00:37:51]What I'm adding? I'm just adding sugar in the water. I'm not going to mix. Now one question for you guys. Tell me from lower classes come out of chemistry to answer these type of question. No need to have masters in chemistry. Tell me sugar in water. It is homogeneous solution or heterogeneous solution. My dear students quickly tell me sugar in water. This is homogeneous solution or heterogeneous solution. First question.

[00:38:18]Second question. In this beaker, how many components we are having?

[00:38:26]Yes.

[00:38:29]Yes. Who is telling that a heterogeneous solution? This is exactly homogeneous solution. This is homogeneous solution.

[00:38:38]We know very well, right? Because sugar can get dissolved in water. We know very well. So, it is a homogeneous solution.

[00:38:46]Now, here what are the components? Is there one solvent that is water, one solute that is sugar. Am I right? Yes.

[00:38:55]Am I right? My dear students, everybody getting an idea right now. Shall I keep this beaker here? I will keep it safely.

[00:39:02]So please be very careful. Now some students are having doubt. Sorry, it is homogeneous or heterogeneous. Let me mix.

[00:39:11]Yes, automatically it will get dissolved. Now I can't sit and mix like right. How preparing coffee in home?

[00:39:17]like that I can't do it now because already we are running out of time right now everybody is getting an idea yes so homogeneous solution sugar in water is the homogeneous solution how many components are there don't see the stick how many components are there only water and sugar we are having two components right so remember one thing when we are having two components when we are having two components that is called as binary solution. Then turnary solution means three components.

[00:39:55]Then what is quattinary solution? We will be having four components.

[00:40:02]Now where majority of the students will get confused means in the representation. Listen carefully. Two components in our syllabus we will be dealing only with binary solution. In our syllabus we will be dealing only with binary solution. Now listen carefully. Binary solution will have two components. What are those two components? That's now I told right. Let me throw the stick. Why stick is required? How many components are there?

[00:40:30]Only two components. One is water another one is sugar. So automatically in two components one solute plus one solvent. Am I right? one solute that is sugar, one solvent that is water. So one solute and then one solvent. So automatically solute is represented by in standard textbook also I will give all the reference solute is represented by number two or alphabet B.

[00:41:04]Solvent is represented by number one or alphabet A. Representation is very very important my dear students. For three components what we can able to tell for three components two solute one solvent.

[00:41:18]For four components three solute one component. It is clear. I think this is very basic. Everyone would have got an idea. Right? Anybody is having any doubts in this type of solution. Anybody is having any doubts. Right? No doubts.

[00:41:33]Right? It is clear. All right. Now my question is identification of solute and solvent. Shall we move further quickly?

[00:41:42]If you want you guys can take a screenshot or else anyhow I will share the notes. So very simple what is solution? It is a homogeneous mixture more than one component will be there.

[00:41:50]It will be having unique characteristics. The next thing type of solution. What are the type of solution?

[00:41:55]On the basis of component binary solution two components will be there.

[00:41:59]One solute one solvent. Turnary solution three components will be there.

[00:42:02]Quattinary solution we will be having four components. It is done. Yes I believe. Done. Understood. Anybody's having any doubts my dear students?

[00:42:11]Clear sir. Very good.

[00:42:15]Everybody is getting an clearcut idea.

[00:42:20]Yes. More than component is of higher order. No need to worry. Yes. Even when it comes to next level of advance also we will be having only turnary solution.

[00:42:30]More than that we won't discuss anything. So if you want to learn about more than four components like that you people master chemistry automatically you guys will learn everything.

[00:42:39]But I'm very happy you people want to read MBBS right so do well my dear students you guys can able to crack then fine now how to identify solute and then solvent that is very very important now we need to understand how to identify solute and solvent Identification of solute and then solvent how to identify how to identify I'm just directly going to ask you guys question okay how to identify solute and solvent let me take if suppose imagine I am taking two components in different phase okay suppose If both components both components means solute and solvent if both components are in different phase. If both components are in different phase then component present in same phase of solution then component present in same phase same face of what? Same face of final solution.

[00:44:21]same face of solution is called solment.

[00:44:31]Now listen one thing my dear students very simple listen one thing now let me take this let me take this what is this sugar solution uh sugar is not dissolved that's fine now tell me what is this is called as sugar solution now what is the solute here solute is sugar what I added right so solute is sugar that is in solid to what I added initially what I was having in my hand only water right beaker containing water so water will be liquid no what is the final I'm getting my dear students what is the final state I will be getting it is a homogeneous mixture sugar solution I will be getting in liquid form so automatically the final whatever the solution I'm getting sugar solution solution the state is liquid. So what is the state of liquid?

[00:45:36]Then which one is having the same state?

[00:45:38]Which one is having the same state? Here liquid here also liquid. Then this is called a solvent. This is called a solute. It is clear. If both the components are in different phase, solid and liquid. Check the solution state. If solution state is liquid, then which is having liquid state? Water. Then that is called as solvent. It is clear. This is one thing. Yes. This is one thing.

[00:46:03]Everything is clear, right? So this is one thing. Next. Yeah. Exactly. I'm coming for the second case. I'm coming for the second case. Next. Give suppose both components are in same phase.

[00:46:20]If both components are in same phase then how we can able to find out? We need to check quantity.

[00:46:34]We need to check quantity then automatically then component presenting higher quantity.

[00:46:51]Which component present in higher quantity? Understand one thing here.

[00:46:55]This is very important in assertion reason point of view. Present in higher quantity means understand one thing. We can talk in terms of moles.

[00:47:05]We can talk in terms of mass. In the same way, we can also talk in terms of volume. Understand this my dear students. Not only moles, we can also explain with respect to the quantity. We can we can express we can express quantity with respect to moles, mass, volume. Then automatically which one is present in higher quantity? The component present in higher quantity is called solvent. It is clear very simple. So we can now able to identify right. Suppose let me take the very best example water 100 ml water plus alcohol 10 ml we will be getting the solution.

[00:48:01]Now understand carefully which is present in large amount water then automatically in this particular example in this particular example if we talk with respect to this example water is the solvent in the same way this will be solute.

[00:48:23]It is clear everybody getting an clearcut idea how to identify solution and sorry how to identify solute or solvent. It is clear. Anybody is having any doubts here my dear students please do let me know quick.

[00:48:37]Yes.

[00:48:40]Clear.

[00:48:42]Anybody is having any doubts?

[00:48:44]No doubts. It is clear.

[00:48:49]Yes.

[00:48:51]Fine.

[00:48:53]Sir, can I get access to the old batches too, sir? Um, that I will check and let you know ma'am. Yeah, sure. Which year batch actually you enrolled? That is also very important. Right. If water is lesser than sugar, then which is present in higher amount that will be the solvent. That's it. Blindly follow the things. That's it.

[00:49:18]Yes, it is clear.

[00:49:21]What about same face and same quantity then we can't able to find out only exceptional question yes but in general solute is less amount solvent is very high amount it is clear okay yes yes how to identify solvent and solution harish that's what I told here yes that is what exactly I told here Done everybody got an idea it's clear so quickly I will give the revision then I will move into types of solution that is very important so when it comes to solution that is the weightage don't get confused sir is teaching solution redux electrochemistry everything in single chart no when it comes to solution what is the idea it is basically a homogeneous mixture of more than one component it is it will be having unique characteristics I'm again and again I'm stressing this point okay next types of solution What will be the type of solution on the basis of component?

[00:50:22]Binary, turnary, quattinary. Binary means two component, one solute plus one solvent. Turnary means three component.

[00:50:28]Quattinary solution means four components will be there. Next, identification of solute and solvent. If both component are in different phase, then component present in same phase of solution is called as solvent. Example this one. If both components are in same phase then component present in higher quantity that is mole mass volume is exactly called as solvent.

[00:50:50]It is clear right? Yes mahalaku. Then shall we move further? What is the universal solvent? Yes I do agree. No doubt in that water is the universal solvent. Okay. Now let me ask one question.

[00:51:04]If water is the universal solvent, which property of water makes it to behave as a universal solvent? Anybody can tell me. Yes. Tell me my dear student. Tell me.

[00:51:17]Yes.

[00:51:19]What property that particular property of water which property of water is making it as it making it to behave as a universal solvent? What is the reason for that? Why water is a universal solvent? Anybody can tell me.

[00:51:34]Why water is the universal solvent? What is the reason?

[00:51:39]Yes. Quick, quick, quick.

[00:51:44]Yes. Why? Water is the universal solvent. Oh, it dissolve because it can dissolve everything, sir.

[00:51:52]Oh, why it is exactly dissolving?

[00:51:56]Yes. Some people is telling dissolves anything. Why it is why it it is having the property to dissolve anything polar protein in other way how we can put in previous dissolving capacity high polarity high polarity little bit shall we go into the physics and tell dialectric constant you people would have studied right dialectric constant how many of you know this term in physics so if you don't know also don't worry sir will teach you guys when it comes to water has very high dialectric constant value. Water has very high dialectric constant value. So that is the reason that value is approximately around 80. That much it is having dialectric constant value. That is the reason. Okay. Now no need to go to physics. We will come back to chemistry.

[00:52:46]We will continue further. It is clear.

[00:52:48]Now quickly each and every one of you know what is solution?

[00:52:53]What are the types of solution based on component? How to identify solute and solvent. You guys can able to do it now?

[00:52:58]Perfect. Now I'm moving into next important thing. Any idea what will be the next very important thing?

[00:53:08]Anybody can tell me types of solution.

[00:53:14]Now in the end of the class questions will be there. Get ready. Types of solution. Now when it comes to types of solution on what basis we are classifying means qualitatively qualitatively.

[00:53:33]Yes sir. It is called also called as relative permitivity types of solution that is qualitatively.

[00:53:40]Now understand qualitatively how I can able to classify solution. First one is based on component. Now second one is qualitatively. Qualitatively what are the two types? Anybody can quickly tell me what are the two types? Very very basic. If I tell you guys can able to tell the ex uh definition. One is a dilute solution.

[00:54:06]Another one is concentrated solution.

[00:54:12]One is a dilute solution. Another one is concentrated solution. Now saturated unsaturated. So when it comes to dilute solution, concentrated solution. Now what is dilute solution? Less quantity of solute for six standard level of writing definition. How I will write in six standard level? Less quantity of solute present in what? Present in given amount of solvent. Less quantity of solute present in given amount of solvent present in given amount of solvent that is dilute solution. This is six standard level.

[00:55:06]Now little bit of neat level if I want to tell means how I can able to tell yes anybody what I can able to write dilute solution one mole of solute can I define like this one mole of solute present in one mole of solute present in 10 liter of solvent. Can you tell in this way?

[00:55:32]Yes. By looking at the thing only one mole of solute present in 10 liter of the solution. So automatically we can keep this under dilute solution.

[00:55:42]What does dialectric constant that is physicsma so relativity of free space and then instead of that if I keep some medium all these things we will be dealing in physics. Don't worry sir we'll teach. So 1 mole of solute present in 10 liter of solvent. If suppose in the same way can I write like this concentrated solution 1 mole of solute present in 100 ml of solvent.

[00:56:14]Qualitatively speaking if I compare between these two can I call this as dilute solution that is concentrated solution. Yes we can able to tell. Yes, we can able to tell. So, how I can write six standard level definition? Hey, nothing wrong in that. We will learn from the scratch. That's it. Nothing wrong in that. Next time if someone ask you any of your junior uh bros just teach us means we should be in the position to teach that is very important. So when it comes to concentrated solution how we can able to define high quantity of solute high quantity of solute present in what? High quantity of solute present in given amount of solvent.

[00:57:07]High quantity of solute present in given amount of solvent. So basically we can able to classify based on qualitatively that is dilute solution and then concentrated solution.

[00:57:19]Now I just introduced solution now we are discussing all the types. Now the next thing first type what we discussed types of solution basis of component next type of solution qualitatively we can able to define the next part is very very important my favorite I'm getting into the chapter please be very careful now types of solution I'm getting into the chapter now listen carefully types of solution basis of what on the basis of phase of solvent types of solution. Now I'm classifying on the basis of pace of solvent.

[00:58:09]On the basis of pH of solvent this is very important now I'm getting into the subject so automatically I will give questions also. Now be very careful how we can able to classify on the basis of face of solution. Remember now if I'm having solvent here what are the faces possible for solvent.

[00:58:35]Solvent can be in solid phase, liquid phase and we will be having gaseous space. Am I right? Solid phase, liquid phase as well as gaseous phase.

[00:58:54]Now types of solution on the basis of solvent state. Now tell me solid phase, liquid phase, gas state.

[00:59:07]Solid phase means then the solution is called as solid solution.

[00:59:14]Liquid phase then it is called as liquid solution.

[00:59:21]Gaseous phase means that is called as gaseous solution. Now in our 12th class syllabus what we are having what exactly we are having? We are exactly having one only this particular topic liquid solution only we are having in our syllabus in 12th class. Whatever the solution we are going to discuss that will be the liquid solution.

[00:59:53]That will be the liquid solution. It is clear everybody. Everyone is clear. Some students asked me some doubt actually based on concentration.

[01:00:04]So didn't understand the concentration in in moles.

[01:00:13]Why? In moles how why you didn't understand in moles? What is the thing?

[01:00:18]Basically concentration is number of moles upon volume. In 11th standard we would have studied this. Concentration is nothing but number of moles present in particular volume. Right? If lesser number of mole present in larger volume.

[01:00:36]Let me do in this way. Let me keep example in this way. 10 moles present in one liter of solution. Next one mole present in one liter of solution. Now tell me which one is having more concentration. Which one is having more concentration?

[01:00:55]Very easy. This one will be having more concentration. Then comparatively speaking, this is the dilute solution.

[01:01:02]This is the concentrated solution.

[01:01:04]Comparatively speaking, this is the comparatively speaking this will be the comparatively speaking this will be dilute solution because 1 mole present in one liter. Comparatively speaking here 10 mole present in one liter. So automatically this is the concentrated solution. This is the dilute solution.

[01:01:25]It is clear. Very clear. Yes.

[01:01:32]Yes. Kashish.

[01:01:34]What happened? Kash what happened?

[01:01:37]Is my voices clear to everyone?

[01:01:40]Is my voice is clear to everyone?

[01:01:44]Everybody can able to understand properly or else I will reduce my mic volume. That will be better I feel.

[01:01:52]Yes.

[01:01:53]Let me reduce my mic volume. Everybody every everybody can able to hear right?

[01:01:58]Yes sir. Yes sir.

[01:02:01]Yes.

[01:02:02]Okay. Okay. Then maybe kashish I think uh okay for better purpose I will reduce my mic volume. Okay then that will work out. Kashish.

[01:02:12]It is clear. Okay. Okay. Fine. Fine.

[01:02:14]Fine.

[01:02:16]Done. Done. Yes sir. Yes sir. Okay.

[01:02:19]Okay. Perfect my dear students. So Kashish I will reduce my mic volume so that it will be very clear.

[01:02:28]Yes. Now it will be fine.

[01:02:31]Okay. See one more thing my dear students if I can't able to read your commands suppose due to when I'm explaining some important concept if I couldn't able to respond immediately means please do wait. I will definitely read the command. Kash. Yes sir. Okay ma. Yes. Hey thanks for letting me know.

[01:02:47]That is also very important. Right?

[01:02:49]Okay. Now you can able to understand with respect to more. Okay. Now we will come here. If the solvent present in solid phase, solid solution, in liquid phase, liquid solution, gasous phase, it is nothing but gasous solution. So these are all the different type of solution.

[01:03:06]It is clear. Anybody's having any doubts? Please do tell me. Anybody is having any doubts.

[01:03:15]Now everything is clear.

[01:03:18]Yes.

[01:03:20]Done.

[01:03:26]Right. Now one basic thing we know very well. If solvent should be in liquid phase then if I take water what is the state of water? Liquid.

[01:03:41]If I take water as a solvent then it is not called as liquid solution. It is called as what? Aquest solution.

[01:03:51]It is called as aquest solution. If water is a solvent then we will be calling it as aquest solution. One of the basic thing that's it done.

[01:04:03]Now the next thing is very very important.

[01:04:08]Yes.

[01:04:11]Okay. Till now I think it is clear for everyone. Now based on this classification we need to discuss some examples. Right. As I told types of solution. You guys can see here I think it will be very clear.

[01:04:27]Types of solution. This please do stick to NCT.

[01:04:36]stick to NCRT.

[01:04:39]One thing I will always tell my dear students, this is the thing I will be always telling to everyone when it comes to chemistry, it is not about memorizing the example or memorizing the stuff.

[01:04:49]Majority even of my colleagues, everyone will tell in organic chemistry we need to memorize the thing. No, chemistry is not about memorizing. It's all about getting familiar with the things. It's all about getting familiar with the things. So please do keep that in mind.

[01:05:07]Do hard work. Okay. One do one thing how I usually remember all the exception trend. You guys can ask me what I will be doing. Now after this class you people will be receiving this class note. Download this class notes.

[01:05:21]Download the class notes. Take print out stick it in your study room or study table.

[01:05:27]What will happen for the next 8 to 10 months? We will be keep on looking into it. If I'm sitting and watching phone, if I'm talking to someone, if I'm watching TV, I'm having dinner with my parents, automatically we can able to keep on looking into that one tablet column, particular tablet column. So things will be registered in our mind. These are all the simple discipline we need to follow. So automatically we will remember all the trends. Even in sleep night 2:00, if I call and ask you, hey tell me what is the trend, you guys can able to tell.

[01:05:59]Exactly. If water is a solvent then we will be calling it as aquest solution.

[01:06:03]If water is a solvent aquest solution of NaOH solvent is water that's it.

[01:06:11]Now this is very very important stick to NCERTT but still I will explain types of solution as I told gasous solution liquid solution solid solution gasous solution solvent will be gas one time is kind enough I don't know my DTP operator written three times okay so liquid solution what will be the solvent liquid in the solid solution what will be the solvent solid you know one thing actually in south India know I'm from South India in movies no whenever this villain is there he will be repeating the punch dialogue for three times four times a solid solid solid gas gas liquid liquid liquid I think in that perspective my DTP operator written like this okay sir can water be solute in a very simple thing I will tell in real life if you take real life water cannot be solute but If suppose I'm sitting in exam some uh random brilliant question paper setter is asking 1 ml of water is present in 100 ml of ether then I don't have any option I need to tell yes water is a solute so but in general it is not there I am from south row yeah then you know right stas like that actually here I'm reading gasous pollution gas gas one time is enough okay so please do keep this in Right. I'm also sir. Okay.

[01:07:44]Sir, which state? I'm from Tamil Nadu.

[01:07:48]Okay. You are from north. Um then you need to watch some South India movie.

[01:07:52]The villain will be talking like that only like that here. Three three times is there. So I'm thought of telling the same.

[01:07:59]Okay. Sahiti I'm South India sir. Okay.

[01:08:04]Good good good. So in the same way we will be don't worry in very few days I will start memorizing everyone name. So automatically I will be calling out each and everyone name. Okay. So don't worry.

[01:08:18]Okay Raki. So definitely I will be calling out each and everyone name like this we will come to know each and everything about us. Okay. All my students are from AP Karnataka. Okay.

[01:08:30]Bangalore sir. Okay.

[01:08:32]Okay. Even though I know Canada Telugu I'm not supposed to speak any other language. Oh Kerala. Okay.

[01:08:40]I see this is what my students see I'm also very bad we both start discussing about movies culture India south India north India everything now we will continue the class I'm from AP okay then okay Bangalore shar okay okay okay from Hyderabad from AP Telangana from up AP sir okay KGF yeah okay AP AP sir native Tamil Nadu AP sir I'm also Tamil Nadu okay okay all south Indians right okay okay nothing wrong in that even five years I was working in one top institution in north India in Delhi after that I was in Vijayada then I was in Bangalore yeah okay then where I studied I studied from uh Gojhati so it's simple okay that's good that's good Ah yes I know uh one thing I will tell my dear students so if you people I'm not supposed to talk in any other language even though I know Hindi my mother tongue Tamil English what we are talking English I can't tell and then Canada Telugu Malayalam these many languages I know as a south Indian I know all the south Indian languages even I know Hindi as well as a little bit Punjab because of Punjabi because of my friends in college I know little bit of Punjabi I so these many languages I know but here I'm not supposed to talk in any other language so it's fine if people ask doubts in any other language also I can able to read so please be very careful okay so gas liquid solid as I told gasous solution means solvent is gas liquid solution means solvent is liquid solid solution means solvent is solid now one thing what will be the solute what are the solute possible yes solute can be gas or liquid or solid. When it comes to liquid solution also gas, liquid, solid is possible.

[01:10:43]When it comes to solid also, gas, liquid, solid is possible. Common examples I given everything. Mixture of oxygen and nitrogen gases. Chloroform mixed with the nitrogen gas. Campfer nitrogen gas. All these three are example. For liquid solution, oxygen dissolved in water. Ethanol dissolved in water. Glucose dissolved in water. Next for solid solution solution of hydrogen in paladium amalgam of mercury with sodium copper dissolved in gold. These are very very important example. One thing I want to tell here my dear students only one small thing I'm going to write here that is very important for us. What I told here these examples and I'll just go through what I told in our syllabus we are having only liquid solution. Now if I talk about liquid solution that is our 12th class first chapter what are the things is possible solvent will be liquid only but what are the possibilities is there what are the possibilities is there solid dissolved in liquid liquid dissolved in liquid gas dissolved in liquid now one thing I'm going to tell please do listen carefully these terminologies you guys can able to see our in our NCERTT textbook solid in liquid that was explained by collleative property that was explained by collleative property liquid in liquid that was explained by R's law gas in liquid That was explained by Henry's law. If you people ask your senior or just randomly if you take and observe your NCERTT textbook we will be having these topics. Yes, in majority of the school they would have started the syllabus. So remember solid in liquid explained by collleative property, liquid in liquid explained by R's law, gas in liquid explained by Henry's law. These things and all I will be discussing in the upcoming classes. As of now just remember in our syllabus we are having only liquid solution. Solid in liquid is collleative property. Liquid in liquid is law. Gas in liquid is Henry's law. It is clear fine.

[01:13:11]Okay dip kumar. Yes. Done. Now in the same way classification of solution based on number of component what we discussed only binary turnary quartinary. Now you guys once again you guys want me to discuss. No example salt dissolve in water. Salt and sugar both dissolve in water. Salt sugar copper sulfate dissolve in water because water is the solvent. One solvent one solvent one solvent. In third case salt, sugar copper sulfate three solute. So quattinary. Salt and sugar two solute.

[01:13:44]So it is turnary. Salt one solute one solvent. Then it is binary. All these things we discussed just now. Next what we are having classification of solution. Just know I told right types of solution.

[01:14:00]Classification based on concentration of solute. Classification based on number of component. Classification based on physical state of solute and solvent.

[01:14:09]All these things we discussed right? It is clear. Next here some wa thing has been happened my dear students based on concentration of solute is dilute and concentrated. See dilute.

[01:14:25]So based on concentration of solute is dilute and concentrated based on number of component is this classification binary turnary quartinary based on physical state gasous solution liquid solution solid solution. In our syllabus we are having only these things. All these things we discussed right. So the next one yes very very important thing.

[01:14:49]So please keep it in mind my dear students. Please do keep this in mind.

[01:14:53]Okay. Brass. Brass is nothing but what?

[01:14:57]If I talk about brass. Brass is a mixture of copper and zinc.

[01:15:03]Bronze. What is bronze? It is a mixture of copper and tin. German silver. What is German silver? Copper, zinc and then nickel. So if I take mixture of copper, zinc, nickel, then it is called as German silver. It is clear. Everything is clear. My dear students is everything is clear. Anybody's having any doubts here?

[01:15:28]It is clear. Now one question will come.

[01:15:32]This brass and bronze how you are remembering sir it is confusing like one small trick I will be using bronze which letter is there Z is there right so I need to write thin brass what is there yes is there so I need to write zinc opposite Z is there so Z will not come yes will come yes is there so yes will not come Z will come that's all very simple simple and that's all it is clear and then it is very clear as simple as that so yes is there Z will come Z is there yes yes yes will come now so these are all about introduction of solution before getting into concentration term now is everyone is ready to solve question if you people are ready please do let me know in the comment session as question type question in the comment section You people really want some 30 seconds time.

[01:16:38]Yes.

[01:16:40]Hey, don't kash don't think about B. Z.

[01:16:45]Z Z Z Z Z Z Z Z Z Z Z Z Z Z Z Z Z Z Z Z Z is there. Yes. Yes. Is there Z copper is fixed?

[01:16:51]Question. Question. Question. Very good.

[01:16:53]Very good. Yes, sir.

[01:16:56]Question. Question. Clear, sir.

[01:16:58]Question. Yes, sir. All right. I think now each and every one of you can able to explain the students. Before starting the question revision is very important.

[01:17:07]Let me tell I will tell the topics just recall whether you guys can able to define or not. Solution types of solution based on number of component types of solution based on state of the solvent. Types of solution based on qualitatively dilute and concentrated. Next one is how to identify solute and solvent. The main thing is based on the state of solvent.

[01:17:35]We will be having solid solution, liquid solution, gasous solution. In our syllabus, we are dealing with liquid solution. In our syllabus, we are dealing with liquid solution. When it comes to liquid solution, what is the important thing you guys need to remember? From tomorrow onwards, I will be keep on asking you guys. Solid dissolved in liquid collleative property. Liquid dissolved in liquid R's law gas dissolved in liquid that is Henry's law these things are also very very important okay since this is the first class initial advice the basic thing I'm starting tomorrow I will be moving into concentration term don't take me lightly marity normality mality mole fraction mole percentage ppm ppb everything I will give all the numericals all the relation so please be very careful now we will continue with the question Okay.

[01:18:26]Yes. Only few questions. My dear students, you guys can easily able to tell. Yes. First question.

[01:18:33]First question. Tomorrow onwards I will keep the poll. Now I will just give the time.

[01:18:40]Homogeneous mixture of two or more than two components is called as what?

[01:18:48]Yes.

[01:18:52]Homogeneous mixture of two or more than two components is called as what yes everybody can able to tell. Good.

[01:19:14]I'm happy. In the same way when I'm teaching advanc level also you guys need to tell that time I don't want the comment like sir what sir you are teaching advanc because my old students told me see one of my student one girl is studying actually now in as buberneshwar that girl now she will be telling sir you are cheating us by teaching advanced things and all like that my dear students then only actually we can able to enter as so get ready to travel with me it will be like a roller coaster ride in chemistry I I'm telling in a positive way so don't worry So automatically solution. All right. No need of explanation. Next question. Which of the following possesses physical state of solute as liquid, solvent as solid? Very important. Don't tell roughly. Think and let me know the answer. Please do think and let me know the answer.

[01:20:10]Please do think and let me know the answer.

[01:20:15]Yes.

[01:20:41]Yes. Three. Three. Three. 3 2 What is the correct answer?

[01:20:54]Very simple my dear students. They told one thing what they clearly told solvent should be solid solute should be liquid.

[01:21:04]When it comes to zinc amalgam remember when it comes to alloys of mercury that is what I want you guys to remember this this is very very important when it comes to alloy of mercury what is amalgam it is nothing but zinc and mercury alloy remember now onwards mercury what is the specialtity it is liquid at room temperature zinc is solid but remember mercury three will always act as a solute.

[01:21:40]This will act as a solvent. So, option two will be the correct answer. Here sugar is solution of sugar. Okay, this should be solution of sugar in water.

[01:21:56]Solution of sugar in water. If I take this option sugar that is solute is solid.

[01:22:08]So here solute is liquid. So A will not come. Now in the same way napalene in benzene brass and all actually it's not alloy of mercury. So remember now onwards make a note in your self note.

[01:22:22]I'm not writing this in a class note.

[01:22:24]Please do make a note when it comes to alloy of mercury. Mercury will present in liquid state that we know very well.

[01:22:31]In room temperature mercury exist as liquid. But what exactly? Mercury will act as a solute. Please do remember when it comes to alloy mercury will act as a liquid. That is when it comes to mercury is a liquid it will act as a solute.

[01:22:47]This is very very important. Amoleia 4 brass. Brass is what just now I told copper plus is there. So zinc will come.

[01:22:54]Both will be in no solid liquid state. H so when only when it comes to mercury it exist in liquid at room temperature that's why we are getting this copper or zinc in room temperature it will exist in solid only right so correct answer is option two no confusion right fine everybody so this is very very important so mercury alloy mercury exist in liquid state it will act as a solute don't forget make a note in yourself note in amalgam of mercury with sodium solvent I told or not the same type of question only they will be keep on asking.

[01:23:35]Yes.

[01:23:37]In amalgam of mercury with sodium solvent is what?

[01:23:53]Yes.

[01:24:04]22 22 22 22 22 22 22 two22 as I told just now my students are very clever mercury automatically liquid so it will act as a solute the question is solvent so the answer will be sodium it is clear so the answer will Soaking up. Next question.

[01:24:29]Match the following.

[01:24:32]Yes. Think and let me know the answer.

[01:24:34]Don't be in a hurry. Haram say the answer. Oh my god. Okay. Let the timer go st. Yes. Timer is running.

[01:24:51]Yeah. Yeah. Yeah. Sure. Uh yeah. I will keep in mind actually today before starting the class I didn't keep from next class I will be doing because this is basic chapter no from next class I will be definitely doing poll because that is my nature even in YT lectures I will keep poll I will drill the students yes B C D E everything they given.

[01:25:26]Yes. Yes. Yes. Quick.

[01:25:48]Everyone got option one.

[01:25:53]One sir, one sir, one sir, one sir.

[01:25:57]Exactly. So how to do that?

[01:26:01]If I want to check, let me check in this way. E, E3, E1, E4, E1. So with the help of E, I can able to take the option hydrogen gas is paladium. Hydrogen gas.

[01:26:15]Hydrogen is in gas. Peladium is solid.

[01:26:18]So what will be happening? Solution of gas in solid. So E is exactly one. If E is one either one, D2, D2, C4 or C3.

[01:26:36]German silver, we know very well German silver. What I given in the notes? What I given in the notes? My dear students, German silver is copper, zinc, nickel.

[01:26:45]All will be in solid. So automatically we know German silver is what solution of solid in solid C4. So C4 option one will be the right answer. But we need to cross check A5 soda water. Yeah. Gas in liquid. Gas in liquid. Yeah. B3 sugar solution. Solution of solid in liquid.

[01:27:09]Now tell me one question. This is what Priti search. Tell me this soda water is there right? Gas in solid. Soda water is gas in sorry liquid. Soda water is gas in liquid. Tell me don't look into the class note. Gas in liquid is explained by collleative property, R's law or Henry's law. D none of the above.

[01:27:34]Which is the answer? Quick tell me. Gas in liquid is explained by which one?

[01:27:40]Collleative property, R's law, Henry's law? None of the above.

[01:27:46]Otherwise tell the name of the law. I will be happy.

[01:27:51]I did in opposite direction sir. Okay no problem.

[01:27:56]Yes everybody. Harris. Hey who is that?

[01:28:00]Tanushri is telling wrong answer.

[01:28:03]Okay. Comment is going very fast.

[01:28:06]Nishika. Yes. Now everyone is giving correct. Who is that? Monisha is correct. They see that Henry is spilling.

[01:28:15]So gas in liquid is explained by Henry's law. Now onwards start remembering all these things. So in the same way liquid in liquid liquid in liquid is R's law.

[01:28:31]In the same way solid in liquid solid in liquid is collleative property.

[01:28:38]CP not C programming collleative property. It is clear my dear students.

[01:28:43]Done. So yes. Next question.

[01:28:50]Which of the following pair of solution having different physical state of solute? Yes.

[01:29:00]Which of the following pair of solution having different physical state of solute?

[01:29:23]solute should have different physical state.

[01:29:29]Yes.

[01:29:55]3 3 3 3 3 1 3 1 3 Now let me check. See, now you people are understanding the point how the question paper setter will frame the question. We need to be very very careful. Brass. Brass is what? Copper solid plus zinc solid. It is in solid state solute. Camperine N2 gas. Campher is actually solid state. So both are solid solid. They told different physical state of solute. So option B is not the answer. Next one here sodium amalgam, sodium solid, mercury liquid. We know only mercury liquid act as a solute.

[01:30:39]When it comes to moist air, what will be happening in moist air? Means liquid water. Moist air. It is nothing but liquid water present in air that is gas. Now understand this is also solute.

[01:30:56]This is also solute. Solute in both same phase. But in the question they are asking different state. Next one solution of H2 gas in paladium. So they clearly told here solute is gas mixture of N2 and O2 there also exactly we will be having gas only. So automatically option A will be the right answer. A we need to check chloroforming N2 gas. What is the state of chloroform?

[01:31:28]Yes. What will be the state of chloroform? Chloroform is actually it is a gas my dear students. No chloroform CH Cl3 is liquid solution of CO2 in water. CO2 is the solute. Solute is present in gas. So solute are present in different phase, different physical state. So option one is the right answer. Everybody got a clearcut idea?

[01:31:56]Yes, everybody got the clearcut idea?

[01:32:01]Done. Okay, next question. Next question is going to be the last question for the day. Try to answer properly. Okay. So that next I will be moving into concentration term from the tomorrow class. Homework is waiting for you guys.

[01:32:16]Do it. Which of the following alternative is correct for physical state of solute and solvent for a solution of campering N2 gas? Camperine N2 gas. What is the correct physical state for solute and solvent? Quick.

[01:32:35]What will be the correct physical state for solute and solvent?

[01:32:44]Yes.

[01:32:48]Yes. One person is telling one others.

[01:32:59]Yes, exactly. Camps are present in solid N2 gas. This is gas. So, solute is solid, solvent is gas. Option one will be the right answer. It is clear my dear students how to do it now. Now, honestly, tell me before I'm winding up the class. Now, it is clear for you guys or not? Tell me honestly.

[01:33:25]Yes.

[01:33:28]Tell me honestly, my dear students. Now these things are clear or not for you guys what is solution everything tell me honestly that's all because the next one academic year you guys are going to travel with me I just want to know whether you people are happy with me in my first class or not so anything you want to tell me now you can tell me in the comment section yes let me give few minutes time yes clear sir clear sir yes sir Clear sir.

[01:34:03]So in the same phase if we continue from tomorrow onwards also. Is that fine my dear students? Crystal clear. Super. We got it. Thank you so much sir. Clear sir. Thank you sir. Crystal clear sir.

[01:34:14]All clear sir. Clear sir. Clear sir. Yes sir. Yes sir. Such a good class. Clear sir. Clear sir. Happy. Amazing class sir. Yeah sir. Clear sir. Okay. I'm just happy to see such a command. Understand sir. Very clear. Thank you for your wonderful lecture. So happy sir. Sajjit clear sir.

[01:34:35]Ah I'm very much clear about your lecture sir. Clear sir. Your teaching is great sir. Got it.

[01:34:45]We are so happy sir. Yes. Good vibes.

[01:34:47]Superb class. Okay. So my dear students that is what I just want to tell. First erase the things like priti sir knows everything. If I tell wrong answer sir will scold. No. My dear students, I will be scolding you guys for sure. If out of our class in front of third person, in front of neat examiner, question paper set in 2027 exam if you guys do mistake definitely I will scold in our class do mistake, learn the things, learn clearly. So many exceptions are there.

[01:35:16]There should not be any gap. You guys are having all right on me. So just ask me any question whatever the concept I'm ready to spend more time also.

[01:35:28]Yes, thank you sir. Thank you. Okay my dear students. Now what is the homework? So in the upcoming days also the class will be like this only we will be continuing concept question. Concept question along with that summary in today class we just completed about introduction to solution. I believe now each and every one of you would have got clearcut idea. So tomorrow class what I will be discussing means that also I'm telling tomorrow I will be discussing concentration term. We are stepping into very important thing. You guys know very well number of questions will come. You make chemistry easy sir. Now I'm interested in chemistry. Yes zin we are going to just rock chemistry that's all.

[01:36:14]Chemistry is easy my dear students. But the approach no we are doing in a wrong way. Nothing to memorize. It's very easy.

[01:36:21]Okay sir, please tell a word in Canada for your Canada students then other students will ask but I'm not supposed to talk. So don't worry one day when we are meeting in person when you score the rank definitely I will come and talk uh I don't have any ideas pandana why what is the problem if you want you can just add no problem it is clear so what is the homework means now DPP is uploaded so solve DPP question that is a daily practice problem now how to solve this daily practice problem very simple download the DPP immediately don't see into the text solution and do no first revise my class notes and try to solve the question if time is there before tomorrow tomorrow class read the NCERTT and come my dear students we will rock okay so that's all so with this I'm finishing our first lecture one more very very important thing if as I told in the beginning of the class today first day some of the students who have not yet enrolled you people can able to listen to my this particular lecture in YT that is for free tomorrow onwards you people won't get such a lecture for that what you guys need to do enroll very simple so you guys can able to see our batches Laksh neat in English 2027 now the price is only 4,200 so without any further delay please do enroll my dear students that is the only thing don't miss the opportunity this is the one time fee. This is just a one-time fee, not monthly monthly. So, please use this opportunity. One more thing, this is our WhatsApp channel QR code. Please do scan this. This is very very important. So, from YT some student is telling for you only I came to PW sir. Yes, Prabha. Very happy. But please do enroll in the app. In the upcoming days also we will be discussing in all the chemistry class. I'm promising not only Praa or YT students whoever is watching my app students everyone will become a master in chemistry. I can assure each and every one of you can able to score 180 out of 180. That's what I'm telling. So please do enroll in our WhatsApp. This is very very important. Last minute some important informations will come in WhatsApp only just now joined sir no problem. So just go through the class I discussed all the important things that is very very important. Okay. So, I will be meeting all you guys in tomorrow class. Thank you so much my dear students. Take care.

[01:39:03]Bye-bye. See you. Fine. Have a great day. Revise and don't forget to solve homework DPP. Approximately only 15 questions are there. Revise the notes and try to solve. Okay. Take care.

[01:39:14]Bye-bye. See you.
