Chromium(III) chloride
Chromium(III) chloride. Uses: Chromium(iII) chloride at elevated termperatures decomposes to chromium( II) chloride and chlorine: 2crcl3→2crcl2 + cl2 heating with excess chlorine produces vapors of chromium(iv) chloride, crcl4. the tetrahedral tetrachloride is unstable, and occurs only in vapor phase. when heated with hydrogen, it is reduced to chromium(II) chloride with the formation of hydrogen chloride: 2crcl3 + h2→2crcl2 + 2hcl chromium(iII) chloride has very low solubility in pure water. however, it readily dissolves in the presence of cr2+ ion. reducing agents such as sncl2 can "solubilize" crcl3 in water. it forms adducts with many donor ligands. for example, with tetrahydrofuran (thf) in the presence of zinc, it forms the violet crystals of the complex crcl3 3thf.
