It forms when an aqueous solution of iodine is treated with mercuric or silver salts. It rapidly decomposes by disproportionation:[1] 5 HOI → HIO3 + 2I2 + 2H2O Hypoiodites of alkali and alkaline earth metals can be made in cold dilute solutions if iodine is added to their respective hydroxides. Hypoiodous acid is a weak acid with a pKa of about 11. The conjugate base is hypoiodite (IO−). Salts of this anion can be prepared by treating I2 with alkali hydroxides. They rapidly disproportionate to form iodides and iodates.[1] References1. ^1 {{cite book|last1=Holleman|first1=A.F.|title=Inorganic chemistry|date=2001|publisher=Academic Press, W. de Gruyter.|location=San Diego, Calif. : Berlin|isbn=0-12-352651-5|edition=1st English ed., [edited] by Nils Wiberg.}} {{Hydrogen compounds}}{{iodine compounds}}{{Inorganic-compound-stub}} 5 : Halogen oxoacids|Hydrogen compounds|Iodine compounds|Oxidizing acids|Oxidizing agents |
