Oil does not dissolve well in water, while many salts dissolve in water. What is the main reason?
Answer and explanation
Correct answer: Nature of solute and solvent differs
Water is a polar solvent, whereas most oils are largely non-polar. Polar water stabilizes ions and other polar particles effectively, so many salts dissolve in it. The interactions between water and non-polar oil are not strong enough to produce good mixing, leading to separate layers. This is summarized by the idea that like dissolves like.
