Q. When during electrolysis of a solution of a ${AgNO}_{3},\ 9650\ C$ of charge pass through the electroplating bath, the mass of silver deposited on the cathode will be
A) 1.08 g
B) 10.8 g
C) 21.6 g
D) 108 g
Explanation
(b)
${Ag}^{+} + \ e^{-}\ \rightarrow Ag$
9650 C = 0.1 F = 0.1 equivalent Ag
= 0.1 mol Ag
= 10.8 g Ag
