1. The reaction of copper sulfate with alkali with the formation of a blue precipitate – copper hydroxide:
CuSO4 + 2NaOH = Cu (OH) 2 + Na2SO4.
2. When heated, hydroxide decomposes into oxide and water:
Cu (OH) 2 = CuO + H2O.
3. Interaction of oxide with hydrochloric acid with the formation of a salt – copper chloride.
CuO + 2HCl = CuCl2 + H2O.
