Answer:CuSO4 (s) + 5H20(l) ----> CuSO4.5H2O(s)
Explanation: starting with an anhydrous copper (ii) sulphate crystal, water is added to form a hydrate. Copper (ii) sulphate is mostly found in the pentahydrate form which means that five molecules of water is used to hydrate it. The resulting hydrate is still solid hence the state symbol (s).
