Sources/Uses

"Metal indicators are organic compounds that form specifically colored metal ion complexes in aqueous media. These dye reactions can be employed for detection of the equivalence point in volumetry (complexometry), as well as for concentration determinations in colorimetry or photometry." [Ullmann] Xylenol orange is used for the complexometric determination of Bi, Ca, Cd, Co, Cu, Fe, Hg, In, lanthanides, Mg, Mn, Pb, Sc, Th, Tl, U, V, Y, Zn and Zr. It is used for the photometric determination of Ag, Bi, Cd, Cr, Fe, Ga, Hg, In, La, lanthanides, Mn, Mo, Nb, Ni, Pb, Sc, Sn, Th, Ti, Tl, U, V, Y, Zn, and Zr. [Ullmann]
