What will be the colour of copper sulphate when iron is added |
|
Answer» Blue to green When iron is added then copper sulphate will be displaced by iron as iron is more reactive metal tham copper and the colour of solution changes blue into green CuSO4 + Fe → FeSO4 + Cu(Blue) (Green)Iron is more reactive than copper. Hence, it displaces copper from copper sulphate solution and due to formation of FeSO4, the colour of solution changes from blue to green. |
