A potentiometric study on the complexation between mercury(II) and phenolate ions

Abstract

Abstract The stepwise stabilities of the complexes formed by mercury(II) with the phenolate and p -nitrophenolate ions have been determined potentiometrically in an aqueous sodium perchlorate medium of unit ionic strength at 25.0°C. In both of the systems studied, only the strong, mononuclear complexes were formed in the range of concentrations used. No evidence has been found for the formation of polynuclear and/or acid complexes.
