Question

Zinc displaces copper from cuso4 solution but silver does not

Answer 1

This is because of its reactivity. zinc is more reactive than copper. if needed refer the reactivity series for more clarity

Answer 2

Answer:

Zinc metal is more reactive than the copper. Moreover, it is placed on the top of the reactivity series. This is why, zinc metal can displace copper from copper sulphate solution but copper cannot displace zinc from zinc sulphate solution.
