The potentials of two reductive half-reactions can be added to obtain the potential of a third reductive half-reaction.

Question

Quizplus · Accepted Answer

The potentials of half-reactions are related to the standard electrode potentials, which cannot be simply added to obtain the potential of another half-reaction. The overall cell potential is determined by subtracting the anode (oxidation) potential from the cathode (reduction) potential.
