Distillation is used to separate mixtures based on its

boiling points

explanation:

distillation is the process of separating mixtures. in practical terms, when we have two or more substances forming a liquid mixture, distillation can be a method for separating them.

an example of distillation dating back to antiquity is the distillation of alcoholic beverages. the drink is made by condensing the alcohol vapors that escape by heating a fermented wort. as the boiling point of the alcohol is lower than that of the water present in the wort, the alcohol evaporates, thus giving the separation of water and alcohol.
