Electrode potentials of successive elementary half-reactions, as commonly represented in Latimer diagrams, cannot be directly added, but can be correctly determined by adding the corresponding Gibbs free energy changes (∆G°) using the general formula ∆G° = – z FE°, i.e., the product of the number (z) of electrons transferred, the ...
