Solution

When a strip of zinc is placed in copper sulphate solution it will displace copper from copper sulphate solution. Zinc is placed above copper in reactivity series of metal. Hence, it will be able to displace copper from copper sulphate solution.
We would observe that the color of the solution will change from light blue to green. The reaction that will take place is the displacement reaction.
Equation:-

$C u S O_{4} + Z n \to Z n S O_{4} + C u$
