Why do metals do not evolve hydrogen gas with nitric acid?

Answers

Answered by AnjaliSapkota191

Hydrogen gas is not evolved when a metal reacts with Nitric Acid because Nitric Acid is a strong oxidising agent.It oxidises the H2 produced to water and itself gets reduced to any of the Nitrogen Oxides (NO, N2O, NO2)

Answered by Ninu2018

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.
