The solution in a beaker turns blue if

A

Cu electrode is placed in `ZnSO_(4)` solution

B

Cu electrode is placed in `AgNO_(3)` solution

C

Cu electrode is placed in `Al_(2)(SO_(4))_(3)` solution

D

Cu electrode is placed in `FeSO_(4)` solution

Text Solution

Verified by Experts

The correct Answer is:
B
Cu being more reactive than Ag due to lower electrode potential, displaces Ag from `AgNO_(3)` solution. It is dissolved in the solution in the form of `Cu^(2+)` ions.
