The colour of copper sulphate solution changes when an iron nail is dipped in it. State the reason giving chemical equation for the reaction involved. |

Answer» CuSO4 + Fe → FeSO4 + Cu CuSO4 -(Blue) FeSO4 - (Green) Iron is more reactive than copper. Hence it displaces copper from copper sulphate and due to formation of FeSO4, the colour changes from blue to green. |
