Question

Assertion : Zinc displaces copper from copper sulphate solution.

Answer 1

Because zinc is more reactive than copper so,therefore it displaces copper from copper sulphate solution

Answer 2

This is so as Zinc is more reactive than copper.
Copper is at the end of the reactivity series.
The more lower a metal is in the reactivity series, the less reactive it is. So the zinc displaces the copper from the copper sulphate solution and becomes zinc sulphate.

This is the chemical equation,

Zn + CuSO42- gives ZnSO42- + Cu.
