Abstract

A numerical method for the evaluation of overlapping acidity constants is proposed in this paper. The method is based on the ratio of absorbances measured at two wavelengths and is rather simpler than the successive approximation methods described by others. The method has been applied to evaluation of the acidity constants of isonicotinic acid.
