represents the distillation of mixture of liquid `A` and liquid `B` which gives both of pure liquid `A` and `B` . Represents the azeotropic mixture of `HNO_(3)` and `H_(2)O` which distillation gives an azeotropic mixture and either of pure liquid. We cannot separate both the pure liquid, i.e., `H_(2)O` and `HNO_(3)`.
What is the result of distilling a mixture of `80% HNO_(3)` and `20%H_(2)O`?
(a)Pure `H_(2)O` and azeotropic mixture can be separated.
(b)Pure `H_(2)O` and pure `HNO_(3)` can be separated.
(c)Pure `HNO_(3)` and azeotropic mixture can be separated.
(d)None of these

Options

A. Pure `H_(2)O` and azeotropic mixture can be separated.
B. Pure `H_(2)O` and pure `HNO_(3)` can be separated.
C. Pure `HNO_(3)` and azeotropic mixture can be separated.
D. None of these

Answer

C

Explanation

The composition of `80% HNO_(3)` and `20% H_(2)O` lies in between the azeotropic mixture and pure `HNO_(3)`. Therefore , distillation of such composition will give pure `HNO_(3)` and azeotropic mixture.
