title: Dissociation constants of arsenazo III.
abstract: 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)).
