For the determination of solubility product $(\mathrm{K}_{SP})$ of $\mathrm{Fe(OH)_3}$, the appropriate cell representation and its emf are, respectively.
(a) $\left.\langle\mathrm{Fe}| \mathrm{Fe}(\mathrm{OH})_{3}(\mathrm{s})\left|\mathrm{OH}^{-}(\mathrm{aq}) \mathrm{Fe}^{3+}(\mathrm{aq})\right| \mathrm{Fe}\right\rangle, \quad-0.750 \mathrm{V}$
(b) $\left.\langle\mathrm{Fe}| \mathrm{Fe}^{3+}(\mathrm{aq}) \mathrm{OH}^{-}(\mathrm{aq})\left|\mathrm{Fe}(\mathrm{OH})_{3}(\mathrm{s})\right| \mathrm{Fe}\right\rangle, \quad-0.750 \mathrm{V}$
(c) $\left.\langle\mathrm{Fe}| \mathrm{Fe}(\mathrm{OH})_{3}(\mathrm{s})\left|\mathrm{OH}^{-}(\mathrm{aq}) \mathrm{Fe}^{3+}(\mathrm{aq})\right| \mathrm{Fe}\right\rangle, \quad+0.750 \mathrm{V}$
