An electrolytic cell contains a solution of $\mathrm{Ag}_{2} \mathrm{SO}_{4}$ and has platinum electrodes. A current is passed until $1.6 \mathrm{gm}$ of $\mathrm{O}_{2}$ has been liberated at anode. The amount of silver deposited at cathode would be
$107.88 \mathrm{~g}$
$1.6 \mathrm{~g}$
$0.8 \mathrm{~g}$
$21.60 \mathrm{~g}$
Solution
$\frac{W_{A}}{E_{A}}=\frac{W_{B}}{E_{B}} ; \frac{1.6}{8}=\frac{W t . \text { of } A g}{108}$
$\therefore$ Wt. of $A g=21.6 \mathrm{~g}$
