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

Options

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.

Answer

C

Explanation

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