A solution of CuSO4 was kept in an iron pot. After a few days, the iron pot was found to have a number of holes in it. Explain the reason in terms of reactivity. Write the equation of the reaction involved.

FeSO₄ is produced when iron displaces the copper which makes the reactivity of iron higher than that of copper. And this nature of iron is responsible for the holes in the pot.

Reaction Involved:

Fe+ CuSO₄ →FeSO₄+ Cu
