| Hazard Information | Back Directory | [Chemical Properties]
dark brown crystalline powder | [Uses]
As indicator in titration of Ca or Mg with EDTA. | [Purification Methods]
A crude dye is extracted with anhydrous diethyl ether and forms red crystals from Me2CO. It gives a red colour in H2O at pH 7—9 and a blue colour at pH 9—11 which turns red on addition of Ca2+ or Mg2+ ions. [Lindstrom & Diehl Anal Chem 32 1123 1960]. Complexes with Ca, Mg and Th. |
