When an iron nail immersed in the solution of copper sulphate than iron displaces copper from the solution of copper sulphate because iron is more reactive than copper. Therefore, the color of copper sulphate changes from blue to green.

Blue colour is due to CuSO4 and green colour is due to FeSO4, since new compound is formed in this change hence this is chemical change.
