Question
Zinc sulphate forms a colourless solution in water. Will you observe any colour on adding copper turning in it?

Answer
There is no colour change on adding copper turning in zinc sulphate solution because copper is less reactive than zinc and it cannot displace zinc from its salt solution. So, displacement reaction does not take place.
