Question:

Calculate the $\mathrm{pH}$ of the cathode compartment for the following reaction given $\mathscr{E}_{\text {cell }}=3.01 \mathrm{~V}$ when $\left[\mathrm{Cr}^{3+}ight]=$ $0.15 \mathrm{M},\left[\mathrm{Al}^{3+}ight]=0.30 \mathrm{M}$, and $\left[\mathrm{Cr}_{2} \mathrm{O}_{7}{ }^{2-}ight]=0.55 \mathrm{M}$.
