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.

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