Answer:
Answer: Aqueous copper sulfate solution is blue from the colour of the hydrated Cu++ cations and since the sulfate anion is colourless. The colour of the copper sulfate does not change during the reaction with magnesium metal.

Explanation:
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 copper sulphate solution colour changes from blue to pale green.
The reaction is
CuSO4 (aq) + Fe (s) → FeSO4 (aq) + Cu (s)
