Question

A zinc plate was put into a solution of copper sulphate kept in a glass container. It was found that blue colour of the solution gets fader and fader with the passing time. After few days when zinc plate was taken out of the solution, a number of holes were observed on it.
i. State the reason for changes observed on the zinc plate.
ii. Write the chemical equation for the reaction involved.

Answer 1

i. Zinc is more reactive than copper and hence, it displaces copper from copper sulphate solution. As a result, a number of holes were observed on the zinc plate.
