Uses
Sulfarsazene is used as a metal indicator for the spectrophotometric and titrimetric determination of Pb2+ ions at pH 9.8–10.0 and Zn2+ at pH 9.3–9.6 (color transition from orange-pink to lemon yellow).[2][3][4]
Physical properties
Sulfarsazene is soluble in water, easily soluble in an aqueous solution of sodium tetraborate, slightly soluble in 95% alcohol, practically insoluble in acetone, chloroform, benzene.
