Further considerations on redox titration equations

The results of an investigation into the dependence of the equivalence-point potential upon concentration and upon the equilibrium constant for the general redox reaction are presented. For symmetrical and homogeneous reactions, the equivalence-point potential is always concentration independent. The quantitative evaluation of the magnitude of the slope of the tangent to the titration curve at the equivalence point for homogeneous and symmetrical reactions is discussed as well as the rigorously calculated values of the potential at 50% and 200% titrated.
