The standard electrode potential$\left(\mathrm{E}°\right)$ for ${\mathrm{OCl}}^{-}/{\mathrm{Cl}}^{-}$ and ${\mathrm{Cl}}^{-}/\frac{1}{2}{\mathrm{Cl}}_2$, respectively, are $0.94\mathrm{V}$ and $-1.36\mathrm{V}$

The$E°$ value for $OC{l}^{-}/\frac{1}{2}{C}_2$ will be

What is the potential of a cell containing two hydrogen electrodes the negative one in contact with${10}^{-8}$

${\mathrm{MH}}^{+}$ and positive one in contact with $0.025{\mathrm{MH}}^{+}\backslash \mathrm{left}({\mathrm{P}}_{{\mathrm{H}}_2}$ is same in both electrodes)?

Calculate the electrode potential at $298 \mathrm{K}$ for $\mathrm{Zn}\mid {\mathrm{Zn}}^{2+}$ electrode in which the concentration of zinc ions is   $0.001\mathrm{M}$ and $\mathrm{E}{°}_{\mathrm{Zn}|{\mathrm{Zn}}^{2+}}$ is $0.74\mathrm{V}$.

Which pair of electrolytes could not be distinguished by the products of electrolysis using inert electrodes?
