Aqueous solution of NaCl is subjected to electrolysis using inert electrodes. Weight of the substance obtained at cathode by passing 9650 amperes of current for 10 seconds will be 

Discharge potential of ${\mathrm{H}}^{+ }$is lesser than that of ${\mathrm{Na}}^{+}$  (or) SRP value of ${\mathrm{H}}^{+}/\frac{1}{2}{\mathrm{H}}_2$ is higher than ${\mathrm{Na}}^{+}/\mathrm{Na}$.

Hydrogen is liberated at cathode.

$$\begin{gathered} \mathrm{q}= \mathrm{i}\times \mathrm{t} ; \\ \mathrm{q}=9650 \mathrm{amp}\times 10 \mathrm{s}=96500 \mathrm{C} ; \\ 96500\mathrm{C} \mathrm{liberates} 1 \mathrm{g}\left(\mathrm{GEW}\right) \mathrm{of} \mathrm{hydrogen} \mathrm{at} \mathrm{cathode} ; \end{gathered}$$
