Okay, so here we have a few different things.
00:05
We want to know if they're soluble in water, which is polar, or pentane, which is a non -polar solvent.
00:26
And so if we remember how things dissolve, like dissolves like is the best way to predict what something will dissolve best in.
00:35
And so here we're saying if something is polar versus non -polar, it's going to dissolve in the polar or non -polar solvent.
00:40
So vegetable oil is non -polar, so it will most likely dissolve in the non -polar solvent.
00:49
Isopropyl alcohol, though, is polar, so it most likely will dissolve in the polar solvent.
00:56
And then last one we have potassium iodide, which is ionic.
00:59
But if we think about what ionic is, it's just a more extreme version of something that's polar, because polar is partial positives or negatives, but ionic is full positives and negatives.
01:10
So something that's polar will easily dissolve something that's ionic.
01:14
So potassium bromide will also dissolve best in water...
