Which of the following statements is/are true about an azeotropic mixutre ?

A

An azeotropic mixture boils at constant temperature

B

The composition of an azeotropic mixture changes on distillation

C

An azeotropic solution of two liquids has a boiling point lower than that of either of them when it shows positive deviation from the Raoult's law.

D

An azeotropic solution of two liquids has a boiling point higher than that of either of them when it shows positive deviation from the Raoult's law.

Text Solution

Verified by Experts

The correct Answer is:
A,B
Azeotropic mixtures are constant boiling mixtures that boil at constant temperature and its boiling point is less than the boilling point of the components.
Hence (A) and (C) are correct answers.
