Added: 2026-05-13

[00:00:00]Hello everyone welcome back to JDC classes.

[00:00:02]So today in the DI Students Sniper 360 degree series, we are going to talk about inorganic chemistry. Today in this video we are going to discuss the inorganic questions from the previous year questions of NIPER. So today we are going to see 25 MCQs in which we will talk about the questions which we have seen in previous year NIPER examinations and today we are going to target Inorganic Chemistry. So let's start today's video with the first question. Example of Lewis acid.

[00:00:36]So example of Lewis acid you have been asked in NIPER JE 2024. You have options like BF3, H2O, NH3, none of these. Look, you all know that Lewis acids are such compounds which have a deficiency of electrons and they want to accept these electrons. If we look at the structures, we know that there is water here, which means oxygen will have two lone pairs. Meaning there are more electrons here. The octet is complete.

[00:01:04]If we talk about nitrogen here, what do we have here? A loan pair will be seen.

[00:01:08]But what we see here is boron trifluoride, what is there next to boron? There are only three valence electrons that can participate in bonds. So boron will form only three bonds here with fluorine and there will be a vacant p orbital lying near it here. So here we have boron, it is an electron deficient species and it can accept an electron pair.

[00:01:32]Because of this, this BF3 will have electron pair accepting tendency here.

[00:01:37]Due to which what we can say is that BF3 will become a less acid here. What are lace acids? Those compounds which have a tendency to accept electron pairs. That's where Lewis used to be based.

[00:01:54]Lewis bases what are they? They have a tendency to donate electron pairs.

[00:01:59]Electron pairs are donors.

[00:02:02]Okay, right? There used to be donors.

[00:02:04]Like he could have donated this to us here. If oxygen was a lone pair, then electrons could have been donated here. Donation could have been made here also.

[00:02:10]So what would boron be here? It will be fine.

[00:02:12]Arrhenius said that acids are those compounds which donate H+ in aqueous solution. They give protons. And bases will be those which give hydroxide that is OH- ions when formed in aqueous solution.

[00:02:23]Bronsted Lowry Theory I. What did he say? Vala Bronstedt said that all compounds that have the ability to donate protons are acids and those that can accept protons are bases.

[00:02:34]Lewis had given his complete theory on electron pairs. The next question is which of the following is not a transition element. Now they have come to the transition elements. Meaning these are d block elements. Transition metals, what we are talking about here, means those compounds which have what? We are talking about d block elements.

[00:02:50]Who has what?

[00:02:53]Where is the last valence electron located? occurs in the d orbital. Iron, yes, definitely comes in D block. Copper also comes in D block. Arsenic and Gold. Gold is also our D block element. There is copper and there is iron also.

[00:03:07]But this arsenic, where does arsenic come from? This is a member of our nitrogen family. So this is a p block element. This is our p block element. So if we are talking about p block elements, can this ever be our transition? No.

[00:03:24]What does D transitions mean?

[00:03:25]What do those electrons do?

[00:03:26]Complexions do. All the formations of the colored complex come. What is our arsenic here? is not a d block element. Not a transition. This is what you were asked. Yes sir, please answer it.

[00:03:40]Which one will be our right answer? We will talk about arsenic here. Which of the following anti- flatulent is usually added to antacids.

[00:03:49]What antifluid is used in antacids? Is it alginic acid, sucralfate, simethicone, or misoprostol? Because we are talking about inorganic here. So all these options we have will become wrong.

[00:04:03]What would simethicone be here in our possession? The right answer will be given. Simethicone is what happens here? There is an antifungal and especially when we talk about antacid preparations, what do we do with it? Do additions. So what is simethicone? We will get the right answer here. This is an anti-fluid substance that does what to the access gas? Removes it from the stomach and intestine.

[00:04:26]Simethicone Commonly What Do We Do? Add to anti-acid preparations.

[00:04:31]Because what happens inside it? It reduces the surface tension of the gas bubbles so what can it do? The bubbles can combine and come out easily. The Jeldol method is used to quantify the Jeldol method. We can say this is a very common question, not just here.

[00:04:49]What is the Jeldol Method? Used for estimation of nitrogen.

[00:04:53]Where do we do what?

[00:04:57]What do we do with nitrogen estimations here? It is used for nitrogen.

[00:04:59]Only organic matter is fine. could have been done.

[00:05:01]But here we have nitrogen.

[00:05:03]So what will we do? I will answer this.

[00:05:04]No metals, no sulfur. So what will be our right answer? It will be nitrogen. Just see how many times you have seen this question in NIPER exams.

[00:05:14]So what is the Jeldol method? What happens to our nitrogen estimation? It is being used. The Jeldol method is what we are talking about.

[00:05:23]In Zeldol method sample containing nitrogen is digested with again another slightly modified question look here it has come.

[00:05:35]During the estimation of nitrogen containing compound in the Jeldol method, with what do we digest it? With whom do you make him react? So what options do you have here? First let's look at concentrated NaOH, concentrated H2SO4, fuming HNO3 or strong ammonia solution. So look, here we are going to use concentrated sulfuric acid. And by what other name is H2SO4 known? We also call it oil of vitriol.

[00:05:59]Oil of Vitriol.

[00:06:01]What is the other name of sulfuric acid? Contains oil of vitriol. So what do we do with this concentrated H2SO4 that we have? First let's get it digested. We get it digested and what do we get? An ammonium sulphate is seen. So what do fathers do with NaOH? It is alkaline. And what do we do with alkaline with NaOH? Then we do it and what is the ammonia in it? It is coming out. And what is ammonia? is distilled and is being titrated. Which of the following acts is Lewis Bass? Who's going to act like Lewis Bess?

[00:06:36]BF3, CO2 and SO2 Ammonia Alf3 Now look carefully here Lewis base means those who have the tendency to donate electron pair, who can donate electron pair.

[00:06:48]BF3 What's next to Boron you just saw? There was a shortage of electrons.

[00:06:53]What are CO2 and SO2? This is neutral. They will not show this phenomenon here.

[00:06:59]Especially CO2 cannot do it at all. Why? Because here we have it clearly visible. Carbon does not have any electrons at all.

[00:07:07]So carbon cannot show here at all.

[00:07:10]Good sir. Coming to ammonia. Hey, absolutely ammonia can do it brother.

[00:07:14]Nitrogen has lone pairs and these are pyramidal structures.

[00:07:19]sp3 hybridisation occurs. So nitrogen has a lone pair which it can donate to accept a proton or to any position which is short of electrons. So it can donate an electron pair. So yes, what is this? Can act as a base.

[00:07:33]So the right answer here is ammonia Alf3, see what is aluminium also?

[00:07:39]It also has a deficiency of electrons.

[00:07:43]Aluminium belongs to the boron family. So what does this even do?

[00:07:45]Forms three bonds. Be it AlCl3 or Alf3.

[00:07:48]So what do we have here? It is an electron deficient species.

[00:07:52]It also has a vacant P orbital.

[00:07:55]So this also means we have electron deficiency.

[00:07:59]What is this even? It is a Lewis acid. Just right answer here will be our ammonia.

[00:08:05]What will happen here if there is NH3? It will be corrected.

[00:08:06]And we have just seen this theory explained in the first question itself.

[00:08:10]Mono acidic bases are called as because mono acidic bases. Look, what do we call those acids? We can call them monobasic or dibasic.

[00:08:25]As many H pluses can be extracted from them.

[00:08:27]Mono acidic bases means bases which can produce how much OH-.

[00:08:32]So here you are basically being asked about the base. Now if there is a base, what will happen in the case of base? OH- Who can produce how much? When they dissolve in water they produce H+.

[00:08:46]How much H+ can they produce when we dissolve them in water? For example, if we take HCL as an example. What will he do? When it breaks down into H+ and Cl-. As soon as it was done, we dissolved it in aqueous water, what will it do, it will produce one H+, so what other name do we give to this hydrochloric acid, there are two names of hydrochloric acid and what do you have to remember, one is muriatic acid, it is called muriatic acid and the other one is its name, spirit of salt, both the names are important, we will have to remember spirit of salt brother, so as soon as we made the aqueous solution, what did it do, it produced one H+, so what is this? This is a monobasic acid. It will be called monobasic acid. But we were asked what was going on?

[00:09:34]We are being asked about mono acidic base.

[00:09:36]So this answer will not be ours here.

[00:09:38]When they dissolve in water they produce one H+ and OH no this is not happening.

[00:09:44]We don't have any such term.

[00:09:46]When they dissolve in water they produce one OH- yes sir. So because it produced an OH- means mono what happened? Mono acidic.

[00:09:57]OH- so it is base. So what is the right answer here? C Both A & C No, this cannot happen.

[00:10:05]What do we have in common? Option C is correct here. This is talking about mono acidic base. This is talking about monobasic acids. You just have to keep this in mind. Okay, right? You just have to keep this in mind. Choose the correct formula for nitric oxide. Nitric oxide is being talked about. N2O2 dye, brother, we are talking about dye nitrogen dioxide.

[00:10:29]Nitric oxide became NO.

[00:10:32]N2O what is this? It's laughing gas, brother.

[00:10:34]This is general anesthesia. So this is the general anesthetic agent that we have been given. Isn't it? What do you call that?

[00:10:43]nitrous oxide. You are talking about nitrous oxide. Isn't it?

[00:10:49]N2O Nun of the then remove it.

[00:10:53]What do its two monomers do when combined? Dyes produce nitrogen dioxide. This NO that we have is nitric oxide. Where are you brother? Here it is. This is our nitric oxide. So what will be option B? Ours is going to be corrected here.

[00:11:08]What is option B here? It is correct.

[00:11:10]Okay, right? What will happen? NO NO NO. Okay, right? Isn't it? N2O2 is nitrogen dioxide. Main constituent of face powder. What is the main constituent of face powder? Tack, zinc oxide, boric acid or soda lime. Hey, all this did not happen at all. Speaking of face powder.

[00:11:29]Talcum powder is the main vehicle. What do we do in this? Many can say deodorants and other things that have a soothing effect, what do we do? Let's add it to this. So the main component of face powder is talcum powder. Talk happens, right? So what will happen to this option? We will have it corrected. Talcum powder what do we have here? It will be right.

[00:11:51]Which of the following is most protophilic?

[00:11:55]Protophilic means that it shows love for protons very easily and very rapidly.

[00:12:00]Meaning who is going to accept H+ faster.

[00:12:03]So what will the best base here do as fast as that? It is going to accept protons. Now look carefully. Here the negative charge is on the carbon. Let's just talk this much.

[00:12:16]Negative charge on carbon, negative charge on chlorine.

[00:12:21]Negative charge on nitrogen and electrical negative charge on oxygen. Sorry. Now you also know one thing that in all these, the presence of negative charge somewhere or the other causes instability. But the more electronegative the charge on an atom, the more stable it is. The more stabilized it becomes. Okay, right? So brother, what is going to happen the most here? We can say that brother is very stable. Isn't it?

[00:12:46]Nitrogen and oxygen are also electronegative.

[00:12:48]But somewhere carbon is not going to be happy here. Isn't it?

[00:12:53]So who will donate his electrons here the fastest and accept H+?

[00:13:00]CH3 negative. Carbo anion, what is this methyl anion? It will accept H+ very fast.

[00:13:07]The faster it accepts H+, the better it is protophilic. The more good the protophilic happened. The base turned out to be just as good.

[00:13:15]We can say this too, brother. The better the base, the faster it will accept H Plus.

[00:13:20]The faster it will donate its electrons. Is it correct? Please tell me. Correct? Good sir. So here we will get orders. Let's see next. Which of the following is the weakest electrolyte? Electrolyte?

[00:13:34]Glucose electrolyte? Hey, this is non-electrolyte brother. Do n't apply electrolyte to it. Urea is also not an electrolyte. Isn't it? Both of these are non- electrolytes. Ephedrine is yes.

[00:13:44]Alkaline. It is of basic nature. Isn't it? This is basic nature. It is an alkaloid. Well then.

[00:13:48]This may be a little bit. Sodium chloride. Hey hey this is the best one here, friend. Isn't it? This is the best.

[00:13:55]And by what name do we know its concentrated solution? Brother, I know it by the name of brine. Isn't it?

[00:14:03]We call the concentrated solution of NaCl as brine.

[00:14:05]What is Effectrin? It is of alkaloid nature. It is alkaloidal. It is of basic nature. If it is of alkaline nature then it says that it is mild for us. I asked you a mild question, right? Let's ask. It is a mild electrolyte but both of these are non-electrolytes. Does not conduct electricity.

[00:14:30]How to know non-electrolyte? Hey, I don't conduct electricity brother. Aqueous solutions do not conduct electricity when dissolved.

[00:14:36]So what is this? It is non- electrolyte. This is strong. You have been asked Week. So you will spend a week. The Fed is the only option we have.

[00:14:44]We have only one option like this. So apply it.

[00:14:46]What is this? It is classified as a weak electrode. It is an organic compound that behaves as a weak base. It is alkaloid in nature, meaning it only partially ionizes in an aqueous solution. Rest of the urea and glucose are non- electrolytes and if we talk about NaCl, then it is a very strong electrolyte.

[00:15:07]Which of the following pK value is shown by the phosphoric acid? Good sir. So this is about H3PO4. Isn't it true sir?

[00:15:19]What is the structure like, sir? Here is its structure. Take this, take this and take this. What is this? This sir is tribasic acid.

[00:15:29]Three H+ can be found here. But the first H plus that comes out will give the lowest pK value. We know what acidic strength is. Now this acidic strength is inversely proportional to the pKa value. The lower the pK, the higher the acidic strength.

[00:15:53]So the PK of phosphoric acid is quite decent.

[00:16:00]It comes around 2.12 to 2.15 approx.

[00:16:04]So here two, three, four, five were given.

[00:16:06]So what will we do here? We will mark the most correct answer. No problem.

[00:16:10]Here the question was value based.

[00:16:12]However, value based questions are not seen much these days. But yes, phosphoric acid is a good acid.

[00:16:18]We are getting to see its PK for the first time in 2.1. Second and third because three is H+. So the first one will go to H+.

[00:16:27]Seconds and thirds. So these were like three H+.

[00:16:32]What will happen if all three are removed? Look, you see the best acid is being seen from the first one coming out. Second, you have got this base of very poor acid. If you look at it one way, what is the third completely? The basics will not come out at all. Isn't it? So if it's triprotic, then H plus can come out three times. We are talking about phosphoric acid.

[00:16:48]According to Arrhenius theory, sado bases are one which sado bases are? Sado bases meant bases that were not producing OH-. Okay, right? Were not doing it. Like ammonia etc. The base is there but what is this RNS accordion? Acido is base. But let's look at the options. Donate OH- OH- who can donate. Good sir. Ok. Donate H Plus this is acid. Accept OH is not possible. Good sir. Ok. There is no Accept H+.

[00:17:19]So now if we talk about Arrhenius here then who is the right answer here? Donate OH- which can give hydroxide can be the same. Isn't it? Now you will say, friend, right now you are saying sir that it will not happen. So let us look at the case of ammonia. If you dissolve ammonia in water, what does ammonia do to the water molecule itself? It breaks into H+ and OH- because it has accepted H+.

[00:17:39]Ammonium ion formed and OH- which is what we have ammonia. Like what have we done to this? If dissolved in water, then let us dissociate something into H+ and OH-. Do we know what nitrogen has? Loan payer. It accepts H+ and forms ammonium. Isn't it? Made something like this. Nitrogen will be positive because it has accepted H+.

[00:18:03]And then here's OH - where did this actually come from? It has come from water only.

[00:18:08]So what has he done? OH- So you produced it, right? OH- Produced. Yes, so who is donating? Which OH- So pseudo base our best answer here is going to be this one.

[00:18:20]Okay, right? What does RS stand for in IP? What does RS mean in IP?

[00:18:26]No reducing substance. Reducing Standard Reference Standard Yes What is GRS? There is a reference standard.

[00:18:34]If we talk then what will be the right answer here? It will become C. RS stands for Reference Standards.

[00:18:42]Okay, right? Reference Standard. And what is this? We are using it for highly purified substances.

[00:18:47]From identification, purity testing, to calibration. We had already seen all these things.

[00:18:52]We saw that in the limit test.

[00:18:53]Reference values ​​were mentioned in some IP for each substance. Which is more acidic? Which is the better acid?

[00:19:03]Now, the question that is being asked here is about inorganic. But this is a very common question and many people get it wrong.

[00:19:09]Maximum people do it wrong.

[00:19:11]HF, HBr, HI and HCL are the simplest ways to do this. Brother, which acid will easily produce H+? You also know that among HF, HBr, HF, HCL, HBr and HI, because hydrogen and iodine have the largest bond length. So the easiest way is to produce H plus your HI.

[00:19:35]So HI is the best acid, hydroiodic acid, iodic acid turns out to be the best acid.

[00:19:42]HF is the poorest acid.

[00:19:45]Even better than HI, we get to see HBr and then HCL.

[00:19:48]So the best acid is HI than our HBr than somewhere HCL hydrochloric acid comes. But I know that maximum people will go with this answer.

[00:19:58]Then we will have HF on fourth, this is very useless. Which is the best acid? HI Along with this, the more stable the conjugate base formed by any acid, the better it is considered to be. Isn't it? The iodide ion is the best stabilized. Why?

[00:20:17]What can a negative charge do to a very large atom? May disperse. Due to which iodide is the more stable conjugate base formed by HI of the acid. For this reason also our HI is considered a good acid. So the best thing is that we get to see the order of HI and HBR and HCL and HF.

[00:20:35]Masking Agent Used for Nick Which masking agent do we use for Nick? Tartaric acid, boric acid, citric acid or barium sulfide? listen very carefully.

[00:20:50]What are masking agents?

[00:20:53]Compounds that mask the reactivity of a particular metal so that it will not react. Isn't it? You will not react. You have the options given here.

[00:21:06]If we talk about nickel, what do we care? Citric acid, well, citric acid is a good masking agent. But if you remember the limit test of iron. In the limit test of iron, we used citric acid to prevent the reactivity of iron and to prevent interference from ammonia or any other metal cation in our reaction. This is especially true of copper metal because copper can be present there many times which can react. So copper could create unwanted products there.

[00:21:39]Here, if we talk about Nick, the masking agent for Nick is tartaric acid. Okay, right? Tartar is acid. We do not use boric acid and this barium sulphide.

[00:21:47]Citric acid is used as a masking agent.

[00:21:51]But the best answer we will use here is tartaric acid which we are going to use as a masking agent for nicks.

[00:22:00]Which one do you use?

[00:22:02]For Nick. For nickel, we use pe here for nick. Okay, right? Well, remember one more thing because the option is not given here, otherwise the best masking agent for nickel should be cyanide, Cn is not in our option, that is why we are doing it like this, tartric acid, because what tartric acid also does here is it reacts, what tartric acid also does is it compresses the reactivity of nickel, it stops it, but the best choice we have for nickel is cyanide, cyanide is the best masking agent, so if cyanide is in the option, then go for it. Who is Niche's Masking Agent Best For? Cyanide. If not, you can apply the answer on tartric acid. The flame color of potassium is dark purple. Liliac Brick Red Green or Blue. Please tell me brother. So what is it brother? Liliac, that's what we're talking about here.

[00:22:58]Okay, right? So what will become of Liliac? It will be right. We are talking about potassium.

[00:23:01]So what happens to potassium? It happens to Lilia.

[00:23:06]Golden yellow is for sodium.

[00:23:07]Brick red is for calcium. And apple green is for barium. So we had potassium talked about. So what will become of Lilia? Violet is what we can see here. Pale violet, right? Come on sir. Which of the following is most polar? Who is the most polar here?

[00:23:27]Chloroform, acetone, water or benzene?

[00:23:32]Chloroform is CHCl3. Isn't it?

[00:23:35]What is chloroform? CHCl3 acetone. ok sir.

[00:23:38]When you talk about water and benzene polarity, water cannot be compared. Isn't it? Who is the most polar here? There is water. Dialectic Constant: Which of these will we see to be the strongest? Water can be seen.

[00:23:52]So what is the strongest thing for us here? There will be water which will be the most polar.

[00:23:56]So C Answer What will happen to us here? will be the right answer. Benzene is non-polar. That 's right brother. Chloroform is fine. It's all right.

[00:24:02]Acetone is also polar. But we see the most polarity in water here.

[00:24:09]In limit test for iron interference of other metal cations is removed by here you go brother. A direct question of limit test came. TGA used to react thio glycolic acid. So what did the ferric ion convert into first? In Ferrous. And this ferrous again reacts with glycolic acid under the presence of citric acid and ammonia.

[00:24:40]So what does it convert to? Ferrous thio glycolate complex Ferrous thio glycolate complex which used to be a purple colour used to be a purple colour complex.

[00:24:56]This citric acid is what does this work. Isn't it? What is citric acid doing to it? causes this reaction.

[00:25:03]So citric acid here prevents interference from other metal cations.

[00:25:05]So, who will we give the right answer to here? We will do it with citric acid.

[00:25:11]What will be option B? Ours is going to be corrected here. Okay, right? It will become citric acid. The limit test for arsenic is done by using the limit test for arsenic, which is not done in a test tube.

[00:25:23]Gadget apparatus is a very important thing and especially now you people will not be able to forget it at all. Isn't it? The question has already come in GPAT.

[00:25:30]Separating Funnel Keepseparates No What is this?

[00:25:35]What do we do with a gadget? Arsenic limit test is done. What do you do here?

[00:25:39]Mercury chloride paper. Hgcl2 paper is also taken.

[00:25:41]We can see a yellow colored stain.

[00:25:44]So our right answer will be here.

[00:25:46]Correct. Remember or not? This is what had come.

[00:25:48]Our hole has a diameter of 2 mm and an internal diameter of 6.5 mm.

[00:25:55]This has been the question of GPAT since 2026. Isn't it? Good sir. Let's go to the next one.

[00:26:02]What does Bayer's reagent do? Oxidation. What does it do in alkenes? Sin is doing the edition of OH. If we talk about ours, this is alkene.

[00:26:12]And what if we did? Bayer's reagent was used. The simplest thing is, if you use Bayer's reagent, what happens to the alkene in the presence of Bayer's reagent?

[00:26:24]Sin Editions Sin Editions of OH are seen. Okay, right? And we get to see carbon single bond one OH another OH attached like this.

[00:26:36]Who is this? Oh, there's nothing else.

[00:26:38]Alkaline Potassium Permanganate Solution 1% What do we call cold dilute alkaline solution of potassium permanganate?

[00:26:46]What is KMNO4 called? It is called Bayer's reagent. It is an oxidizing agent. It is an oxidizing agent.

[00:26:54]So yes, what will be the right answer? We can put B here. What do we call cold dilute alkaline potassium permanganate solution? Bayer's reagent is speaking.

[00:27:06]Unsaturation is used for testing. If there is unsaturation then you will get diols. What do we do to identify the presence of double and triple bonds? Let us see that unsaturated compounds decolorize the purple colour of alkaline KMnO4 because alcohols have been formed there.

[00:27:20]Which is not an antiperspirant? Which is not an antiperspirant?

[00:27:26]Meaning, who is not one of those who stops sweating? Who is not stopping? Just check it.

[00:27:32]Aluminum Sulphate, Aluminum Chloride. Look, aluminum compounds are especially present in our aerosols and deodorants.

[00:27:39]Why? Because they contain antiperspirant action. ok sir.

[00:27:43]So both ways were added as well. Strontium sulfide, look, this is not going to happen here at all. Can anyone tell me where we can find strontium sulfide, strontium chloride etc.?

[00:27:55]Where did we use this strontium chloride? You guys tell me quickly in the comment section. So this stodium sulfide of ours is not used here.

[00:28:03]Ok? Russell's salt is a ha ha sodium potassium tartrate what is osmotic osmotic laxative is laxative sodium potassium tartrate sodium potassium tartrate hydrogen potassium tartrate not copper sulphate CuSO4 what is an emetic agent and what is the common name? What is its common name? Quickly friend, please tell me a little about this and also remember everything else and tell me.

[00:28:44]Is? So the correct answer will be sodium, potassium tartrate. Apart from this, what is another compound that we read about?

[00:28:53]MgSO4, common name of magnesium, is Epsom salt or bitter salt. What happens to us as well? Saline cathartics or what we call osmotic leg will also be done. This is where Graham's salt is a synonym of Graham's salt is a synonym of what? Sodium monofluorophosphate, sodium metaphosphate, calcium carbonate or dibase calcium phosphate? Where is it used? This is a toothfish. This is what we use in our Dentiface. This is also used in our dental floss. And this is used in dentifrice, it is used as an abrasive agent. Isn't it? The erosive agent used is calcium carbonate. Sodium Meta Phosphate. Yes sir.

[00:29:37]What will happen to this? It will be corrected here. of Graham's Salt. This synonym is NaPO3, now what can be there in it, it may increase, but yes, its empirical formula is this, which we can see, chemically zeolite is, what is zeolite chemically, it is nitrate of aluminium, silicate of aluminium, yes, it is absolutely correct, not magnesium silicate, not calcium silicate, silicate of aluminium, what do we call this, zeolite especially works as a very good catalyst, is n't it? So this zeolite is a very good catalyst. Aluminum silicate what will happen here? We will get to see the correct answer. So what is B option? It will be corrected here. Hydrated aluminium silicate is composed of sodium, potassium and calcium.

[00:30:28]This aluminium silicate is used in classified applications such as water softening.

[00:30:34]We see this in ion exchange material catalysts and adsorbents.

[00:30:38]So these were the questions of Organic Chemistry for you today in this NIPER 360° series which we have already seen in previous year NIPER examinations. I hope you guys enjoyed asking questions in this video and I will meet you guys very soon with some more new questions and some more new topics. Thank you so much. Till then, have faith in your exam preparation.

[00:31:03]You are going to do very well and you are going to qualify this examination with a good rank.
