Hi, in this question we are given that table salt and water are not soluble in solvent a but they are soluble in solvent b and it is also given that vaseline and vegetable oil are soluble in solvent a but they are not soluble in solvent b.
00:20
We are asked to explain the polarities of solvent a and solvent b.
00:26
We can say that table salt is nacl, it is having na plus ions and cl minus ion.
00:35
We can say it is an ionic compound and it is polar in nature.
00:46
If we talk about water that is h2o it is also a polar solvent and according to a theory that says like dissolves like it means the polar molecule will be soluble in polar solvent.
01:03
Hence the table salt and water will be soluble in polar solvent from which we can say that the solvent b is polar in nature.
01:20
If we talk about the second part which says vaseline and vegetable oils are soluble in solvent a.
01:27
We know that vaseline and vegetable oils are the organic compounds and organic compounds are insoluble in polar solvent.
01:41
Hence we can say that vaseline and vegetable oils are soluble in the solvent a which is non -polar in nature...
