Characteristic
Chromium(III) fluoride is the name for the inorganic compounds with the chemical formula CrF3 as well as several related hydrates. The compound CrF3 is a green crystalline solid that is insoluble in common solvents, but the coloured hydrates [Cr(H2O)6]F3 and [Cr(H2O)6]F3•3H2O are soluble in water. The trihydrate is green, and the hexahydrate is violet. The anhydrous form sublimes at 1100–1200 °C.
Chemical formula:CrF3
Molar mass : 108.9913 g/mol
Appearance: green crystalline solid
Density: 3.8 g/cm3
Melting point: 1,100 °C (2,010 °F; 1,370 K) (sublimes)
Solubility in water: negligible
Solubility: insoluble in alcohols; soluble in HF, HCl
Magnetic susceptibility (χ): +4370.0•10−6 cm3/mol
Application
Chromium(III) fluoride finds some applications as a mordant in textiles and as a corrosion inhibitor. Chromium(III) fluoride catalyzes the fluorination of chlorocarbons by HF.
