Q. To deposit one equivalent weight of silver at cathode the charge required will be

AMUAMU 2002

Solution:

One faraday is that quantity of electricity which can be deposited or liberated weight equal to equivalent weight.
$1 $ faraday $=96500 C$
Let the required charge to deposit one equivalent weight of silver be $Q$.
Equivalent weight $=\frac{Q}{F}$
$1 =\frac{Q}{96500} (1 F =96500\, C ) $
$Q =96500 \,C =9.65 \times 10^{4} \,C$
