Question

How would you determine the standard electrode potential of the $M{g}^{2+}$ $|Mg$?

Answer 1

To determine the electrode potential of $m{g}^{+2}/m{g}^1$ we use hydrogen electrode (anode)

The standard hydrogen electrode potential is zero.

$\therefore E^{o}cell=E^{o}right+E^{o}left$

$E^{o}cell=E^{o}m{g}^{+2}/m{g}^{-1}{E}^o{n}_2/n_1$

$E^{o}m{g}^{+2}/mg=E^{o}cell$
