Question

the liquid mixture which boils without changes in composition is called....​

Answer 1

Explanation:

The solution which distills without change in composition at a particular temperature is called azeotropic mixture. An azeotropic mixture is a mixture of two liquids having the same boiling point. ... These mixtures are thus called constant boiling mixtures. These are formed by non – ideal solutions.

Answer 2

Answer:

An azeotrope or a constant boiling point mixture is a mixture of two or more liquids whose proportions cannot be altered or changed by simple distillation.[2] This happens because when an azeotrope is boiled, the vapour has the same proportions of constituents as the unboiled mixture. Because their composition is unchanged by distillation, azeotropes are also called (especially in older texts) constant boiling point mixtures.
