Question

Why is it that we can not react nitric (IV) acid with metals to produce hydrogen gas

Answer 1

Nitric acid is not reacted with metals to form hydrogen gas because it is a strong oxidizing agent and therefore it forms nascent oxygen which further combines with hydrogen gas forming water and our motive never gets fulfilled.

Answer 2

★ HERE IS YOUR ANSWER ★

_________________________

When a metal reacts with dilute nitric acid, then hydrogen gas is not evolved. Nitric acid is a strong oxidising 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.
