Question

Which of the following method(s) is/are not used for separation of azeotropic mixtures?

• A. Steam distillation
• B. All of the above.
• C. Simple distillation
• D. Fractional distillation

Answer 1

The correct option is B All of the above.

Distillation technique is used to separate volatile substance from non-volatile compound in a mixture i.e., they have their individual different boiling point temperature.

Azeotropic mixture is a liquid mixture of two miscible liquids which distill over without changes in composition.

These azetropic mixture boils at a same temperature rather than the boiling temperature of individual liquids.
Hence, during boiling the composition remains same.
So, azeotropic mixture are not separated by any of the distillation techniques.
