Question

Reacting of nitric acid with metals does not evolve nitrogen gas.Give reason​

Answer 1

Nitric acid(HNO3) is a strong oxidising agent. The Hydrogen gas produced during its reaction with metal gets oxidised to H2O, hence no hydrogen gas is produced. Instead it evolves nitric oxides such as NO2,NO etc.

Answer 2

Answer:

Explanation:

Nitric acid(HNO3) is a strong oxidising agent.

The Hydrogen gas produced during its reaction with metal gets oxidised to H2O, hence no hydrogen gas is produced.

Instead it evolves nitric oxides such as  NO2,NO etc.

For Eg:

Cu(s) + 4HNO3(aq)--->Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l)
