| Chromous Iodide, CrI2, can be prepared by the action of hydrogen iodide on chromium at a red heat, or by the reduction of chromic iodide by means of hydrogen. Reduction in solution produces a hydrate associated with a salt of zinc. Chromous iodide is a greyish- white powder, soluble in water; the solution absorbs oxygen, giving a green solution. Its general properties are similar to those of the other chromous halides. |
