Question

Nitric acid being a strong oxidizing agent is used in the preparation of hydrogen.

• A. True
• B. False

Answer 1

The correct option is B False

Nitric acid (${\mathrm{HNO}}_3$) is a strong oxidizing agent and so it oxidizes hydrogen gas produced in water.

Hydrochloric acid($\mathrm{HCl}$) or sulphuric acid(${\mathrm{H}}_2{\mathrm{SO}}_4$) are preferred because they do not oxidize hydrogen formed in the water and so hydrogen gas formed can be collected over water.

Therefore the given statement is false ie., nitric acid being a strong oxidizing agent is used in the preparation of hydrogen.
