When iron rod is kept dipped in copper sulphate solution for some time

1.	When iron rod is kept dipped in copper sulphate solution for some time, a brown coating is formed on the iron rod. What change will be observed in the colour of the solution? Also write chemical equation for the reaction involved
Answer» Blue colour of the solution changes to light green. Reddish brown deposit is formed on the iron nail. Fe(s) + CuSO₄(aq) → FeSO₄(aq) + Cu(s)
