Question

Zinc sulphate forms a colourless solution in water. will you observe any colour on adding copper turnings in it? state the reason why there is a colour change, with the reactions involved.

Answer 1

We will not observe any colour change when we add copper turnings to it as Zinc is more reactive than Copper and that means it will not be able to take over the properties of Zinc Sulphate. It will not be able to displace Zinc from its salt to form CuSO4. Copper turnings by themselves would not be able to change the colour of the solution.
