Characteristic
Chromium(III) chloride (also called chromic chloride) describes any of several compounds of with the formula CrCl3 • xH2O, where x can be 0, 5, and 6. The anhydrous compound with the formula CrCl3 is a violet solid. The most common form of the trichloride is the dark green hexahydrate, CrCl3 • 6H2O.
Chemical formula： CrCl3
Molar mass：158.36 g/mol
Appearance：purple
Density： 2.87 g/cm3
Melting point：1,152 °C (2,106 °F; 1,425 K)
Boiling point：1,300 °C (2,370 °F; 1,570 K) decomposes
Solubility in water：slightly soluble
Solubility：insoluble in ethanol;insoluble in ether, acetone
Acidity (pKa):2.4 (0.2M solution)
Magnetic susceptibility (χ):+6890.0·10−6 cm3/mol
Crystal structure:YCl3 structure
Application
Chromium chloride and chromium sulfate have been used as dietary supplements. Chromium(III) chloride and chromium(III) sulfate can be used in the manufacture of food for particular nutritional uses and in food supplements. It is found in miscellaneous applications, such as catalysts, hardeners, mordents, crosslinking and binding agents. It is used to make very pure chromium and other chromium compounds, as a mordant in dyeing cotton, and in chromizing metals. It is too used for trivalent electroplating .
