Are following reaction problem? Clear answer with reason.

(i) Cu + ZnSO₄→ CuSO₄ + Zn

(ii) Fe + CuSO₄→ FeSO₄→ FeSO₄ + Cu

(i) Cu + ZnSO₄→ CuSO₄ + Zn

The above replacement reaction is not possible because Copper is less reactive then Zinc. Hence, it would not able to replace Zinc from its compound (ZnSO₄₎.

(ii) Fe + CuSO₄→ FeSO₄→ FeSO₄ + Cu

The above replacement reaction is possible because Copper is less reactive then Iron. Hence, Iron would easily replace copper from its compound (CuSO₄ ) to form ferrous sulphate( FeSO₄).
