Question

A zinc plate was put into a solution of copper sulphate keep in a glass container it was found that blue colour of the solution get fader and Fader with passage of time after a few days when zinc plate was taken out of the solution a number of holes were observed on it. a) .state the reason for change observed on the zinc plate.
b). write the chemical equation for the reaction involved.​

Answer 1

Answer:

zn+ cu (so)4= zn (so)4 + cu

Answer 2

This has occured because displacement reaction is taken here.

" The chemical reaction in which more reactive element displaces less reactive element from its compound is known as displacement reactions.

Here, zinc is more reactive than the copper hence it displaces copper from copper sulphate.

Chemical equation:

Zn + CuSo4 → ZnSo4 + Cu
