Iodige acid, the oxygen acid of iodine, in which this occurs in the III oxidation state. Its salts are called Iodite. It is the last and least stable representative in the series of halogen oxyacids. Currently, over iodige acid, little is known. It can not be isolated and also in aqueous solution only a very reactive intermediate is that arises, for example, in the disproportionation of hypoiodous acid in sodium hydroxide (in the form of his Säurerestions ):

Iodige acid disproportionation even at temperatures around 0 ° C rapidly hypoiodous acid and iodic acid:
