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 a salt.
СuO + 2HCl = CuCl2 + H2O.
3. The reaction of salt with alkali – precipitation of copper hydroxide in the form of an insoluble precipitate.
CuCl2 + 2NaOH = Cu (OH) 2 + 2NaCl.
