Approximation of oxidation-reduction titration curves by logarithmic functions

摘要

The approximation of potentiometric oxidation-reduction titration curves by logarithmic functions provides precise determination of the equivalence point for reactions with different stoichiometry. The relative error in the determination of the equivalence point for the titration of iron(II) with cerium(IV) and bichromate at concentrations of about 5 x 16~(-4) M is lower than 0.1%.
