1. Combustion of copper in excess of oxygen at a temperature of 400-500 ° C.
2Cu + O2 = 2CuO.
2. The reaction of copper oxide with nitric acid to form a salt.
2CuO + 2HNO3 = Cu (NO3) 2 + H2O.
3. The reaction of exchange of copper nitrate and potassium hydroxide.
Cu (NO3) 2 + 2KOH = Cu (OH) 2 + 2KNO3.
4. Interaction of copper hydroxide with hydrochloric acid with the formation of copper chloride.
Cu (OH) 2 + 2HCl = CuCl2 + 2H2O.
