Write the reaction equation: Cu-CuO-Cu (NO3) 2-Cu (OH) -CuO-CuO4-CuCl-Cu (NO3) 2
1. Copper (II) oxide is obtained as a result of copper oxidation.
2 Cu + O2 = 2CuO.
2. Copper (II) nitrate is obtained as a result of the reaction of oxide and nitric acid.
CuO + 2HNO3 = Cu (NO3) 2 + H2O.
3. Copper (II) hydroxide is obtained by the interaction of copper nitrate and alkali.
Cu (NO3) 2 + 2NaOH = Cu (OH) 2 ↓ + 2NaOH.
4. Copper oxide is obtained by decomposition by heating copper (II) hydroxide.
Cu (OH) 2 = CuO + H2O.
5. As a result of the reaction between copper oxide and sulfuric acid, copper sulfate and water are obtained.
CuO + H2SO4 = CuSO4 + H2O.
6. The products of the reaction between copper sulfate and hydrochloric acid are copper (II) chloride and sulfuric acid.
CuSO4 + 2HCl = CuCl2 + H2SO4.
7. Copper nitrate is obtained by the reaction of copper chloride and nitric acid.
CuCl2 + 2HNO3 = Cu (NO3) 2 + 2HCl.
