The standard oxidation potential E⁰ for the half cell reaction are

$\begin{array}{l}\mathrm{Fe}\to {\mathrm{Fe}}^{2+}+2{\mathrm{e}}^{-};\hspace{0.25em}\hspace{0.25em}\hspace{0.25em}\hspace{0.25em}{\mathrm{E}}^{\circ }=+0.41\mathrm{V}\\ \mathrm{Cu}\to {\mathrm{Cu}}^{2+}+2{\mathrm{e}}^{-};\hspace{0.25em}\hspace{0.25em}\hspace{0.25em}\hspace{0.25em}{\mathrm{E}}^{\circ }=-0.34\mathrm{V}\end{array}$

EMF of the cell reaction is

$\mathrm{Fe}\left(\mathrm{s}\right)+{\mathrm{Cu}}^{2+}\left(\mathrm{aq}\right)\to {\mathrm{Fe}}^{2+}\left(\mathrm{aq}\right)+\mathrm{Cu}\left(\mathrm{s}\right)$
