1. The decomposition of copper nitrate at 180 ° C.
2Cu (NO3) 2 = 2CuO + 4NO2 + O2.
2. Reaction of oxide with acid.
CuO + 2HCl = CuCl2 + H2O.
3. Reaction of salt with alkali – formation of insoluble copper hydroxide.
CuCl2 + 2NaOH = Cu (OH) 2 + 2NaCl.
4. Reaction of hydroxide with sulfuric acid
Cu (OH) 2 + H2SO4 = CuSO4 + 2H2O.
