1.To obtain copper from copper chloride, it is necessary to carry out a reaction with a more active metal than copper, for example, iron. The reaction product is copper (precipitates) and iron (II) chloride.
CuCl2 + Fe = FeCl2 + Cu ↓.
2. Copper is oxidized by oxygen to copper (II) oxide.
2Cu + O2 = 2CuO.
3. Copper oxide, reacting with nitric acid, form copper nitrate and water.
CuO + 2HNO3 = Cu (NO3) 2 + H2O.
4.In the interaction of copper (II) nitrate and alkali (sodium hydroxide), copper (II) hydroxide and sodium nitrate are formed.
Cu (NO3) 2 + 2 NaOH = Cu (OH) 2 ↓ + 2 NaNO3.
