The amount of manganese in steel is determined by changing it to permanganate ion. The steel is first dissolved in nitric acid, producing $\mathrm{Mn}^{2+}$ ions. These ions are then oxidized to the deeply colored $\mathrm{MnO}_{4}^{-}$ ions by periodate ion $\left(\mathrm{IO}_{4}-\right)$ in acid solution.a. Complete and balance an equation describing each of the above reactions.b. Calculate $\mathscr{E}^{\circ}$ and $\Delta G^{\circ}$ at $25^{\circ} \mathrm{C}$ for each reaction.
