A solution of CuSO4 was kept in an iron pot. After 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.

Answers (1)

Iron displaces copper from copper sulphate solution as it is a more reactive metal than copper. The reaction is as follows:
Fe\left ( s \right )+CuSO_{4}\rightarrow FeSO_{4}+Cu
A portion of the iron pot gets dissolved and cause holes in this process.
Iron taking part in this reaction, produces holes at places where iron metal has reacted to form iron (Il) sulphate.
