Cathode (Reduction +)

Copper (Cu)

Cu2++2eCu(s)Cu^{2+} + 2e^- \rightarrow Cu(s)
Ered=+0.34VE^\circ_{red} = +0.34 \, V

Anode (Oxidation -)

Zinc (Zn)

Zn(s)Zn2++2eZn(s) \rightarrow Zn^{2+} + 2e^-
Ered=0.76VE^\circ_{red} = -0.76 \, V
Ecell=EcathodeEanodeE^\circ_{cell} = E^\circ_{cathode} - E^\circ_{anode}
Ecell=(+0.34)(0.76)E^\circ_{cell} = (+0.34) - (-0.76)
