write two reaction when HNO3 react with metal to form H2O
Answers
Explanation:
Explanation:
When metals react with nitric acid hydrogen gas is liberated.
Nitric acid is a very strong oxidizing agent.
So , it oxidizes the hydrogen gas formed during the reaction to form water and an oxide of nitrogen (NO,N2O,NO2 etc.).
The reaction for it is:-
Zn+4HNO3→Zn(NO3)2+2NO2+2H2O
Exception:-
Magnesium and manganese react with very dilute nitric acid to liberate hydrogen gas.
The reaction for it is:-
Mg+2HNO3→Mg(NO3)2+H2
