Chapter 18, Problem 18.153CP

The following galvanic cell has apotentialof1.214V at 25 °C:

$\text{Hg}\left(l\right)\left|{\text{Hg}}_2{\text{Br}}_2\left(s\right)\left|{\text{Br}}^{-}\left(0.10\text{M}\right)\right.\right.‖{\text{MnO}}_4{}^{-}\left(0.10\text{M}\right),{\text{Mn}}^{2+}\left(0.10\text{M}\right),{\text{H}}^{+}\left(0.10\text{M}\right)\left|\text{Pt}\left(s\right)\right.$

Calculate the value of $K_{sp}$ for ${\text{Hg}}_{\text{2}}{\text{Br}}_{\text{2}}$ at 25 °C.
