摘要
The approximation of acid-base titration curves by logarithmic functions is an efficient method for the determination of the equivalence point even for the titration of dilute solutions of electrolytes of intermediate ionic strength. The relative error in the determination of the equivalence point for the titration of 4 x 10(-4)-5 x 10(-3) M solutions of dichloroacetic, chloroacetic, benzoic, and boric acids is no higher than 1%.
