Q. During the electrolysis of a solution of ${AgNO}_{3},\ 9650\ C$ of charge is passed through the electroplating bath. The mass of silver deposited at the cathode will be
A) 108 g
B) 10.8 g
C) 1.08 g
D) 18.10 g
Explanation
(b)
${Ag}^{+} + e^{-} \rightarrow Ag$
96500 C charge liberates silver = 108 g
$\therefore$ 96500 C will liberate silver = 10.8 g
