Calculate the $\mathrm{E}_{\text {cell }}^{\circ}$ of $\mathrm{Al}\left|\mathrm{Al}_2\left(\mathrm{SO}_4\right)_{3(\mathrm{M})} \| \mathrm{HCl}_{(\mathrm{IM}) \mid}\right| \mathrm{H}_{2(\mathrm{~g})(\mathrm{latm})}, \mathrm{Pt}$ (Given $\mathrm{E}_{\mathrm{AB}^{3+\mid}|\mathrm{A}|}^{\circ}=-1.66 \mathrm{~V}$ )
  1. 1.66 V
  2. -1.66 V
  3. 0.0533 V
  4. 1.14 V

Solution

$\begin{aligned} E_{\text {cell }}^o & =E_{\text {cathode }}^0-E_{\text {anode }}^o \\ & =0-(-1.66 \mathrm{~V})=1.66 \mathrm{~V}\end{aligned}$
