A solution of copper sulphate was kept in an iron pot. After a few days, the iron pot was found to have a number of holes. Write the equation for the reaction that took place. Exlain in terms of reactivity.

Explanation

`CuSO_(4)+FetoFeSO_(4)+Cu`
When copper sulphate is stored in an iron pot, iron being more reactive than copper displaces copper from its solution. So, after a few days we find holes in the pot.
