Quizplus · Accepted Answer

The standard cell potential (E°cell) is calculated by subtracting the reduction potential of the anode (E°anode) from the reduction potential of the cathode (E°cathode). Given E°red for Zn^2+/Zn is -0.763 V and for Cu^2+/Cu is +0.340 V, the Zn/Zn^2+ acts as the anode (oxidation) and Cu^2+/Cu acts as the cathode (reduction). Thus, E°cell = E°cathode - E°anode = 0.340 V - (-0.763 V) = +1.103 V.
