Abstract

The stability constant for isosaccharinic acid dissociation is of importance in complexation studies involving species present in radioactive waste. As there are very few stability constants reported in the literature, this study has determined stability constants at 22.8, 34.5 and 44.2° C, using potentiometric titrations in a 1 M NaClO4 solution. The stability constants were linear functions of the inverted temperature, thus allowing for a simple determination of the entropy and enthalpy of the reaction.
