Ferric Chloride, also know as Iron(III) chloride, and Iron chloride, is an industrial scale commodity chemical compound. In its raw form, ferric chloride is a hygroscopic crystal. Its color is dependent on the viewing angle. In reflected light, the crystals appear to be dark green. By transmitted light, they appear purple-red. Ferric chloride is readily soluble in liquids with donor properties, such as alcohols, ketones, ethers, nitriles, amines, and liquid sulfur dioxide, but sparingly soluble in nonpolar solvents like benzene and hexane according to Ulmann’s Encyclopedia of Industrial Chemistry.
