Solutions Investigation

Added: 2026-05-23

[00:00:00]Okay, so this is um the solutions investigation just to kind of get you guys started um so that you guys can kind of explore some of things in a solution. Um the link to the FET is on classroom, so you want to go ahead and click on that and you want to use I'm going to write it up here, but you want to click on not um download, but you want to click on the one that is ran by something called cheap R J, I think.

[00:00:30]Um that's the one you want to click on.

[00:00:32]It will take a moment to load, um but just go ahead and click on it. Once you click on that, then what you should see Hopefully, I can get that for you. What you should see Okay, is this. Okay, so this is what you should see here um when you press play.

[00:00:53]Okay, when you press play, you're going to go ahead and um see that. Okay, and you're going to click here on the micro tab. So, you want to um look at the micro tab um cuz you want to see it at the micro level.

[00:01:09]So, in the um atoms level cuz since we're in chemistry. And so, the first thing you're going to do is you're going to um look at sodium chloride. So, remember it's going to ask you on the paper based on the chemical formula sodium chloride um what kind of compound it is. And remember you're talking about those three compounds we learned in bonding, so you're talking about is it ionic, is it covalent, or is it uh metallic? And so, you would look at these. Remember, an ionic is a metal plus a nonmetal. Um a metallic is metals bonded together, and then a covalent is all nonmetals.

[00:01:47]So, you're going to determine um one of the first questions for both of them is sodium chloride, sucrose, what kind of compounds? You're going to choose one of those three um to write on your paper.

[00:01:57]And then when you get there, what you're going to do is you're going to shake you're just going to grab it, click it, and then grab it and shake it back and forth. You're going to shake some sodium chloride into the water. And you're going to see what happens to the atoms, okay? And so, um, you're going to see, um, what's happening to the atoms. It's not that they're dissolving, right? But you can see that they're separating. So, with sodium chloride, this type of compound actually separates atoms, okay?

[00:02:24]And so, then what you're going to do is you can also look at the concentration, you guys, um, right here, and you can see that sodium and chlorine are the same, um, concentration, okay?

[00:02:38]And then you're going to test and see if it actually, um, conducts electricity. And the way you're going to do that is if you go back to the macro tab here, conductivity, you're going to go ahead and you're going to put the light in there, and then again, you're going to shake some salt here on the macro, okay? And you're going to see, does this conduct electricity? If it conducts electricity, then that light's going to go on, and you can see the yellow, okay? And if you need to reset, then you're going to go ahead and reset tab, and then start all over. And you can see this is not on, okay?

[00:03:14]All right. And then, you're going to draw that. So, when you draw what you see, you're going to draw from the macro tab.

[00:03:21]Um, so you're going to look at what does sodium chloride look like as a solid, okay? And when [snorts] you shake it, you can see it. And then what does it look like when it's dissolved in water?

[00:03:32]And then you're also going to do, uh, glucose. And when you're talking about, um, what it looks like in water, you can go ahead and look here, and you can see what this is what you'll draw sodium chloride solid looks like, and it looks like this. So, this is what you'll draw for the solid. And then when you put it into water, you're going to drop it in here, and you're going to go ahead and then draw this is what it looks like in water. So, you can see that it separates with separate atoms and then the water is there as well. Okay? So, that's what goes in the box. And then you're going to go back to your micro tab and you're going to switch to glucose here. And there's periodic table to determine if it's an ionic, covalent, or metallic compound.

[00:04:18]And you're going to shake in sucrose.

[00:04:21]Okay? And then you're going to see what happens with sucrose itself. Okay?

[00:04:27]And you can see it's going around. And you're going to answer those questions.

[00:04:32]So, does it separate or do the atoms separate or not? And then of course, you're going to go back here and you're going to determine if you click sugar, is this going to conduct electricity if I shake shake some sugar in there.

[00:04:46]Okay?

[00:04:47]All right. And then, of course, just like you did with sodium chloride, when you reset all, reset all, we're going to remove that salt from there. And then you're going to take sugar and this is what sugar should look like as a solid.

[00:05:01]You're going to draw that in your box.

[00:05:03]And then you're going to put it in and you're going to see that it's going to stay together. It's not going to separate. And you're going to draw that dissolved in water. And please use color in your drawings.

[00:05:13]Okay?

[00:05:14]And then the last part of the last one is called evaporation. So, you're going to go to the micro tab for this evaporation part.

[00:05:22]Okay? And we're going to reset all.

[00:05:25]And you're going to start with sodium chloride.

[00:05:29]Shake it back in there.

[00:05:31]And then what you're going to do is you're going to evaporate all the water.

[00:05:33]And to do that, you're going to take this tab, you're going to hold it, and you're going to slide it to lots of evaporation until all the water is gone.

[00:05:41]And pay attention to what's happening to those atoms as we get rid of all the water. And you see they start sticking together again, okay? And then you're going to do that same thing for sucrose, okay?

[00:05:55]All right, so let's switch back to our paper. So, remember you can write this down if you like, okay? Is, okay?

[00:06:05]For this one, as we get to our paper here, okay? Put it back up. Remember, you're going to answer these questions these questions you're going to answer, okay?

[00:06:17]From the micro tab, okay?

[00:06:20]These you're going to draw from the water tab, okay? You'll draw what they look like from the water tab.

[00:06:26]Um the results in the electricity, that's going to be on the macro tab, okay? Same for here, okay? 1 through 3 is going to be on the micro tab.

[00:06:39]Um fourth one will be on the macro tab.

[00:06:42]And then this would be on the water tablet.

[00:06:47]And then these last two questions here, you're going to do on the micro tab, okay?

[00:06:53]All right, so you can check your answers when you're done, all right? Have fun.
