Question
Explain why, metals usually do not liberate hydrogen gas with dilute nitric acid.

Answer

Metals do not liberate hydrogen gas with nitric acid because nitric acid is a strong oxidizing agent. So, as soon as hydrogen gas is formed in the reaction between a metal and dilute nitric acid, the nitric acid oxidises this hydrogen to water.
