When zinc is added to CuSO(4) solution, ...

When zinc is added to `CuSO_(4)` solution, copper is precipitated. It is because of

A

Oxidation of `Cu^(+2)`

B

Reduction of `Cu^(+2)`

C

Hydrolysis of `CuSO_(4)`

D

Ionization of `CuSO_(4)`

Text Solution

Verified by Experts

The correct Answer is:
B

In this reaction `Cu^(2+)` change in `Cu^(0)`, hence it is called as reduction reaction.
