HNO3 + Cu = Cu(NO3)2 +NO2+ H20
HNO3 + Zn = Zn(NO3)2 + NO2 + H20

The results of Zn or Cu reactions with nitric acid at various concentrations are different.
1. The interaction between zinc or copper and weak nitric acid is as simple as:
4Zn + 10HNO₃ → 4Zn(NO₃)₂ + N₂O + 5HO
When Zn or Cu reacts with weak nitric acid, they generate Nitrous oxide.
2. The following is the reaction of zinc or copper with strong nitric acid:
Zn+4HNO₃(conc.) → Zn(NO₃ )₂ +2NO₂ +2H₂O
Zinc produces nitrogen dioxide in the presence of concentrated nitric acid.
- Because concentrated nitric acid is a powerful oxidizing agent and zinc is a good reducing agent, a violent reaction is likely.
- A wide range of products can be formed depending on the temperature of the reaction mixture, and numerous processes can occur at the same time. Overall, it's a complicated set of reactions with different stoichiometry depending on the situation.
