Question

give reason:
hydrogen gas is not produced when a metal reacts with Dil nitric acid.​

Answer 1

Answer:

HOPE THIS HELPS

Explanation:

This is because nitic acid is a strong oxidizing agent so instead of producing hydrogen it is going to produce water.

Answer 2

Answer:

Hydrogen gas is not evolved when a metal reacts with nitric acid. It is because HNO3 is a strong oxidising agent.

Explanation:

Hydrogen gas is not evolved when a metal reacts with nitric acid. It is because HNO3 is a strong oxidising agent. It oxidises the H2 produced to water and itself gets reduced to any of the nitrogen oxides (N2O, NO, NO2). But magnesium (Mg) and manganese (Mn) react with very dilute HNO3 to evolve H2 gas.
