The solution of copper sulphate fades and finally becomes light green on dipping a rod made up of iron. When an iron nail is dipped in CuSO4 solution, a brown coating of Cu is formed on the surface of iron and the colour of CuSO4 solution changes for blue to light green. This reaction shows that Fe is more reactive than copper as it displaces copper from its solution and green colour FeSO4 solution is formed.
