Question

explain the process of casting iron nails in solution of Cu SO4. ( including chemical equation)​

Answer 1

Answer:

When an iron nail is dipped in copper sulphate solution, a brown coating of copper is formed in the surface of iron and the colour of the copper sulphate solution changes from blue to pale green. The reaction shows that iron is more reactive than copper because it displaces copper from the copper sulphate solution.

Explanation:

Fe + CuSO₄    →      FeSO₄ + Cu
