Question

Give reason hydrogen is not evolved when a metal reacts with nitric acid

Answer 1

Answer:

Yes, because nitric acid is a highly oxidizing agent.

Explanation:

Hydrogen gas is not evolved when a metal such as potassium and calcium reacts with nitric acid to form nitrates, water and releases Nitrogen dioxide, nitrogen oxide and oxides of Nitrogen. It is because nitric acid is a highly oxidizing agent. So, when nitric acid is reacted with any metal such as potassium metal and calcium metal to form water because nitric acid contains much amount of oxygen and nitric acid is highly oxidising agent. So, nitric acid is capable of producing or adding oxygen in any substances. Here, nitric acid makes hydrogen into water by giving oxygen atoms.
