Dissociation constants of arsenazo III.
Commercial samples of Arsenazo III were found to be appreciably impure even after purification as the barium salt. Chromatography on silica gel followed by crystallization yielded a pure sample of the ethanol solvate of the free acid. The dissociation constants of the acid were determined potentiometrically at 25 degrees and I = 0.1 (NaClO(4)).
