Solution

According to Faraday's first law $W = Z i t$ .
Given: $W = 10.07$ gm,
$i = 5$ ampere,
$t = 30 \times 60$ seconds
$∴$ $10.07 = Z \times 30 \times 60$
$Z = \frac{10.07}{5 \times 30 \times 60} = 0.00111888$
and by $\frac{W_{1}}{W_{2}} = \frac{E_{1}}{E_{2}} = \frac{Z_{1}}{Z_{2}}$
$= \frac{E q u i v a l e n t m a s s o f s i l v e r}{E q u i v a l e n t m a s s o f H y d r o g e n}$
$= \frac{E l e c t r o c h e m i c a l e q u i v a l e n t o f S i l v e r}{E l e c t r o c h e m i c a l e q u i v a l e n t o f h y d r o g e n}$
$\frac{E q u i v a l e n t w e i g h t o f S i l v e r}{1} = \frac{0.00111888}{0.00001036}$
Equivalent weight of silver $= 108$
