Abstract
The Generalized Approach to Electrolytic Systems (GATES/GEB) is the recommended paradigm applicable to thermodynamic formulation of electrolytic redox systems of any degree of complexity where Generalized Electron Balance (GEB) completes the set of equations needed for quantitative description of the redox system tested. Two equivalent Approaches (I, II) to GEB are formulated herein for the potentiometric titration in the (FeSO4 + H2C2O4 + H2SO4, KMnO4) system (D+T system) and in related subsystems, (D1+T) and (D2+T), taken as formal examples. Among others, the general criterion distinguishing between redox and non-redox systems is indicated. Further regularities related to these systems are clearly reported.
