Question:

The solutions that show large negative deviation from Raoult’s law forms which type of azeotropes?

Options:

Minimum boiling azeotrope

Maximum boiling azeotrope

Does not form an azeotropic mixture

None of these

Correct Answer:

Maximum boiling azeotrope

Explanation:

The solutions that show large negative deviation from Raoult’s law form maximum boiling azeotrope at a specific composition. Mixture of Nitric acid and water is an example of this class of azeotrope. This azeotrope has the approximate composition, 68% nitric acid and 32% water by mass, with a boiling point of 393.5 K.
