The solubility product of $\mathrm{AgBr}(\mathrm{s})$ is $5 \times 10^{-13}$ at 298 K . If the standard reduction potential of the half-cell, $\mathrm{E}_{\mathrm{Ag\mid AgBr}(\mathrm{s}) \mathrm{Br}^{-}}^{0}$ is 0.07 V , the standard reduction potential $\mathrm{E}_{\mathrm{Ag}^{+} \mid \mathrm{Ag}}^{0}$ (in volts) is ____ .
