\({\mathrm{E}}_{\mathrm{cell}}={{\mathrm{E}}^{0}}_{\mathrm{cell}}-\frac{\mathrm{RT}}{\mathrm{nF}}\ln \frac{\left[{\mathrm{Mg}}^{2+}\right]}{{\left[{\mathrm{Ag}}^{+}\right]}^{2}}\)

\({\mathrm{E}}_{\mathrm{cell}}={{\mathrm{E}}^{0}}_{\mathrm{cell}}-\frac{\mathrm{RT}}{\mathrm{nF}}\ln \frac{{\left[{\mathrm{Ag}}^{+}\right]}^{2}}{\left[{\mathrm{Mg}}^{2+}\right]}\)

\({\mathrm{E}}_{\mathrm{cell}}={{\mathrm{E}}^{0}}_{\mathrm{cell}}+\frac{\mathrm{RT}}{\mathrm{nF}}\ln \frac{\left[{\mathrm{Mg}}^{2+}\right]}{\left[{\mathrm{Ag}}^{+}\right]}\)

\({\mathrm{E}}_{\mathrm{cell}}={{\mathrm{E}}^{0}}_{\mathrm{cell}}+\frac{\mathrm{RT}}{\mathrm{nF}}\ln \frac{\left[{\mathrm{Ag}}^{+}\right]}{\left[{\mathrm{Mg}}^{2+}\right]}\)
