Okay, so here we can't, the question is, what can we do if we do not know which layer is in an extraction procedure, so which is organic and which is aqueous? so if you have, depending on what your organic and your aqueous layers are, what you can do is you can add more of your organic solvent to the mixture.
00:21
And if the organic layer increases, then you know then which one that is.
00:26
And if the top layer increases, then, or sorry, if the other layer increases, then that would be your aqueous layer.
00:35
So here we want to consider the densities of the pairs and consider which was on top and if they form two layers.
00:45
So hexane's density is 0 .65 grams per cubic centimeter, whereas waters is 1 .00.
00:55
So hexane will be on top.
00:59
Water and these two are not missable so we will have two layers.
01:07
Then we have ethanol and water.
01:12
So ethanol's density is 0 .789...
