Question

Why doesn't azeotrophic mixture distill without any change in composition?

Answer 1

Explanation:

During the distillation of the azeotropic mixture, all the components of the mixture boil at the same temperature and the resulting vapours have the same ratio of constituents as the original mixture. ... Therefore an azeotropic mixture distills without any change in composition

Answer 2

Answer:

An azeotrope is a mixture of liquids that boils at a constant temperature, at a given pressure, without change of composition. In other words, an azeotrope is a multicomponent mixture that performs in distillation as if it was a single component. ... When the azeotropic liquid is boiled, it retains the same composition.
