Question

A zinc plate was put into a solution of copper sulphate kept in a container.It
found that blue colour of the solution gets fader und der with the passage of time. After
few days, when zinc plate was taken out of the solution a number of holes were observed
on it
(1) State the reason for changes observed on the zinc plate
(2) Write the chemical equation for the reaction involved.

​

Answer 1

1. The Zinc metal is more reactive than copper. So it displaces copper from its solution to form Zinc Sulphate. That's why holes are formed in zinc plate.

2.

Zn + CuSO4 - - - - > ZnSO4 + Cu.

Hope it helps.
