$Zn$ gives $H_{2}$ gas with $H_{2} SO_{4}$ and $HCl$ but not with $HNO_{3}$ because:NEET 2002

Options:

Answer:

Solution:

Nitric acid $(HNO_{3})$ is a strong oxidising agent. The Hydrogen gas produced during its reaction with metal gets oxidised to $H_{2} O$ , hence no hydrogen gas is produced. Usually when $Zn$ reacts with acid, it acts as a reducing agent which gets oxidised to a salt and the acid is the oxidising agent which gets reduced to hydrogen gas.
