Chemistry - Ionic Equilibrium Question with Solution | TestHub

To find the $K_{sp}$ of ${\mathrm{AgBrO}}_3$, a student prepared one litre of a just saturated solution by adding ${\mathrm{AgBrO}}_3$at 27°C. He found that a copper wire left in the solution overnight became covered with silver, and ${\mathrm{Cu}}^{2+}$ (aq) ions were also formed in the solution. The wire was cleaned, dried, and found to weigh 7.04 mg less than it did originally.

($R=8J/mol/K$; $\ln x=2.3\log x$)

$\mathrm{Cu}\left(\mathrm{s}\right)+2{\mathrm{Ag}}^{+}\left(aq\right)\rightleftharpoons {\mathrm{Cu}}^{2+}\left(aq\right)+2\mathrm{Ag}\left(\mathrm{s}\right)$

Given: $\Delta G°=-110.4kJ$.
