Question
One half$-$cell in a voltaic cell is constructed from a silver wire dipped in silver nitrate solution of unknown concentration. The other half$-$cell consists of a zinc electrode in $1.0 \ M$ solution of $Zn(NO_3)_2.$ A voltage of $1.48 \ V$ is measured for this cell. Use this information to calculate the concentration of silver nitrate solution.
[ Given, $E_{\mathrm{Zn}^{2+} / \mathrm{Zn}}^{\circ}=-0.763 \mathrm{~V}$ and $E_{\mathrm{Ag}^{+} / \mathrm{Ag}}^{\circ}=+0.80 \mathrm{~V}$ ].
