Answer:
Zinc is more reactive than copper and hence displaces copper from copper sulphate solution and forms zinc sulphate. Answer: Copper is less reactive than zinc. Hence, copper cannot displace zinc from a compound. Hence, no reaction takes place when copper turnings are kept in zinc sulphate solution.

Answer:When zinc is added to copper sulphate (CUSO4) solution due to more reactivity of zinc, cooper is replaced by the zinc and forms zinc sulphate. During the process, the colour of the solution changes from blue to colourless.
The chemical equation of the reaction,
Zn + CuSO4 → ZnSO4 + Cu
