The solution which boil at constant temperature like a pure liquid and possess same composition in liquid as well as vapour state are called azeotropes. The components of azetropes cannot be separated by fractional distillation. Only non-ideal solutions form azeotropes. Solutions with negative deviation form maximum boiling azeotrope and the solutions with positive deviation form minimum boiling azeotrope. The boiling point of an azeotrope is never equal to the boiling points of any of the components of the azeotrope.
Answer the following question:
The azeotropic mixture of water and `HCl` boils at `108.5^(@)C`. This solution is

Options

A. ideal
B. non-ideal with positive deviation
C. non-ideal with negative deviation
D. cannot be predicted

Answer

C
