 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. 

Text Solution

Verified by Experts

Iron (Fe) is more reactive than copper (Cu). Therefore, Fe displaced Cu from copper sulphate solution and forms `FeSO_(4)`. This reaction results in formation of holes in the iron pot. The reaction involved is given below:
`CuSO_(4) + Fe rarr FeSO_(4) + Cu`
