Concentrated nitric acid is a strong oxidizing agent. It is used for oxidizing most metals. The products of oxidation depend on the concentration of the acid, temperature, and also on the material undergoing oxidation.

3Cu + 8HNO3(dilute) → 3Cu(NO3)2 + 2NO + 4H2O

Cu + 4HNO3(conc) → Cu(NO3)2 + 2NO2 + 2H2O
