title: Spectrophotometric examination of redox equilibria by use of logarithmic transformations.
abstract: For the spectrophotometric characterization of redox reactions, a logarithmic transformation is proposed by which it is possible to analyse indirectly the functions E = f (pH) and E = f (C) derived from experimental data. Besides the mechanism of the reaction the equilibrium constant can also be calculated. The method is generally usable for equimolar redox systems and also for non-equimolar ones if a single equilibrium exists in the range under examination. References to the evaluation are given and the practicability is demonstrated with the system Fe(3+)/SO(2-)(3).
