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 • 6H2O
Molar mass：266.45 g/mol
Appearance：dark green
Density： 1.760 g/cm3
Melting point：83 °C
Boiling point：1,300 °C (2,370 °F; 1,570 K) decomposes
Solubility in water：585 g/L
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(III) chloride hexahydrate is used as a catalyst, as a mordant in printing and dyeing industry. It is involved in the preparation of anhydrous tetrahydrofuran complex of chromium(III) chloride by reacting with trimethylsilylchloride. It finds application in the manufacturing of a variety of chromium-containing pigment in Paint industry and other chromium salts in the chemical industry.
