| | CALMAGITE Usage And Synthesis |
| Chemical Properties | dark brown crystalline powder | | Uses | As indicator in titration of Ca or Mg with EDTA. | | Uses | Calmagite is widely used in analytical chemistry as an indicator in the titration of calcium or magnesium with ethylenediaminetetraacetic acid (EDTA). It is also useful in the determination of magnesium in biological materials. | | Uses | Used for the determination of magnesium in biological materials. | | 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. |
