Question
The reduction potential ( $\mathrm{E}^0$, in V ) of $\mathrm{MnO}_4^{-}(\mathrm{aq}) / \mathrm{Mn}(\mathrm{s})$ is $\_\_\_\_$ . [Given $\mathrm{E}_{\left(\mathrm{MnO}_4^{-}(\mathrm{aq}) / \mathrm{MnO}_2(\mathrm{~s})\right)}^0=1.68 \mathrm{~V} ; \mathrm{E}_{\left(\mathrm{MnO}_2(\mathrm{~s}) / \mathrm{Mn}^{2+}(\mathrm{aq})\right)}^0=1.21 \mathrm{~V} ; \mathrm{E}_{\left(\mathrm{Mn}^{2+}(\mathrm{aq}) / \mathrm{Mn}(\mathrm{s})\right)}^0=-1.03 \mathrm{~V}$ ]
