Question

Nitric acid cannot be concentrated beyond 68% by the distillation of dilute solution of $HN{O}_3$

• A. True
• B. False

Answer 1

The correct option is A

True

Nitric acid cannot be concentrated beyond 68% by the distillation of dilute solution of $HN{O}_3$ because it forms an azeotropic mixture i.e; at ${121}^{o}C$ it boils without any change in its concentration of the mixture with water.
