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 hydrochloric acid to form copper chloride.
CuO + 2HCl = CuCl2 + H2O.
3. The reaction of exchange of copper salt with aluminum with the formation of aluminum chloride.
3CuCl2 + 2Al = 2AlCl3 + 3Cu.
