प्रश्न
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.
उत्तर
According to the reactivity series of metals, iron is more reactive than copper and hence can displace copper from its salt. When a solution of copper sulphate is stored in the iron pot, a displacement reaction happened and iron from the pot came into the solution forming iron sulphate and thus the holes were formed in the pot.
