Why hydrogen is not evolved when a metal react with nitric acid |
|
Answer» 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. Because it is a powerful oxidizing agent which oxidize the hydrogen. Cause it is strong oxidising agent. |
