In a galvanic cell,the salt bridge is used to:

The $Cu^{+}$ ion is not stable in aqueous solution. For the disproportionation reaction,what is the $E^o$ value in $V$? (Given: $E^o_{Cu^{2+} | Cu^{+}} = 0.15 \, V$; $E^o_{Cu^{2+} | Cu} = 0.34 \, V$)

$Cu^{+}_{(aq)}$ is unstable in solution and undergoes simultaneous oxidation and reduction,according to the reaction $2 Cu^{+}_{(aq)} \rightleftharpoons Cu^{2+}_{(aq)} + Cu_{(s)}$. Choose the correct $E^{\circ}$ for the above reaction if $E^{\circ}_{Cu^{2+}/Cu} = 0.34 \ V$ and $E^{\circ}_{Cu^{2+}/Cu^{+}} = 0.15 \ V$.
