Cadmium Sulfodichlorohydroxydimethylfuchsondicarboxylate Chelate—A Spectrophotometric Study

Abstract
Sulfodichlorohydroxydimethylfuchsondicar-boxylate forms a 1:2 violet colored chelate (λmax 540 mμ) with cadmium(II). The chelate is stable between pH 9.5 and 11.5. The values of stability constant as determined by two different methods are 9.1 and 9.0, at 25°C.
