CALMAGITE Usage And Synthesis

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.
