Expert Answer:

Zinc is more electropositive (Eθ = - 0.76V) and therefore, is highly reactive metal. Hence, it cannot be easily displaced from its solution of ZnSO4. On the other hand, copper is less electropositive (Eθ= + 0.34 V) and can be readily displaced from its solution by some more

active metal such as zinc.
