Calcium Hypoiodite

When iodine is allowed to react with calcium hydroxide and water at the ordinary temperature, in addition to an iodide and iodate, a compound supposed to be analogous with chlorine bleaching powder is obtained in solution. It is colourless, has an odour strongly suggestive of iodoform, and, although moderately stable in the dark, is readily decomposed by heat and light. It is supposed to consist either of a mixture of hypoiodite and iodide or of the compound CaI(OI).

According to Wilks iodine is adsorbed by slaked lime.
