Question

Metals like copper fail to evolve hydrogen gas on reacting with dilute nitric acid.

Open in App
Solution

1) Nitric acid(HNO3) is a strong oxidising agent.

2) 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.

3) For Eg:

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

Sodium aluminate and hydrogen gas are formed,

when sodium hydroxide reacts with aluminium metal.
