Problem

A constant current was passed through a solution of

\text{AuCl}_4^-

ion between gold electrodes. After a period of

10.0

minute the increase in mass of cathode was

1.314 \text{ g}

. The total charged passed through solution is : (atomic mass of

\text{AuCl}_4 = 339

) a.

1.16 \times 10^{-2} \text{ F}

3.5 \times 10^{-2} \text{ F}

2 \times 10^{-2} \text{ F}

4 \times 10^{-3} \text{ F}
