What would happen if you add zinc coated iron nail into the solution of copper sulphate ? Give reason for your prediction. |
| Answer» Solution :The zinc COATED iron nail will react with the `CuSO_(4)` and the blue COLOUR of the solution gradually fade and after SOMETIME solution will turn GREEN because, now, iron nail will react with the copper sulphate. This happens because iron and zinc both displace the copper of copper sulphate solution because iron and zinc both are more reactive than copper. | |
