प्रश्न
Illustrate how copper metal can give different products on reaction with HNO3.
उत्तर
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 + 8HNO_(3(dilute)) -> 3Cu(NO_3)_2 + 2NO + 4H_2O`
`Cu + 4HNO_(3("cone")) -> Cu(NO_3)_2 + 2NO_2 + 2H_2O`
