During the reduction of Gold (III) from ...

During the reduction of Gold (III) from `AuCl_(4)^(-)` ion, the solution must be stirred rapidly during electrolysis. The stirring is important because

A

It helps to separtae gold from chlorine

B

It increases the movement of `AuCl_(4)^(-)` towards anode

C

It overcomes the repulsion between the `AuCl_(4)^(-)` and the excess `e^(-)` at the electrode and help in deposition of gold (III)

D

It increases the conductivity of the solution.

Text Solution

Verified by Experts

The correct Answer is:
C
God in `AuCl_(4)^(-)` has to be reduced at an electrode with excess electron. Hence, stirring is essential.
