$A$ solution of $CuSO_{4}$ 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.

(N/A) $Fe$ is more reactive than $Cu$. According to the reactivity series,$Fe$ can displace $Cu$ from its salt solution.
When $CuSO_{4}$ solution is kept in an iron pot,$Fe$ reacts with $CuSO_{4}$ to form $FeSO_{4}$ and $Cu$ is deposited.
This reaction causes the iron pot to corrode,leading to the formation of holes.
The chemical equation for this displacement reaction is:
$Fe(s) + CuSO_{4}(aq) \rightarrow FeSO_{4}(aq) + Cu(s)$
