Hypoiodous acid is a ] with a ] of about 11. The ] is '''hypoiodite''' ({{chem2|IO−}}). Salts of this ] can be prepared by treating ] with ]s. They rapidly disproportionate to form ]s and ]s.<ref name = "Wiberg&Holleman"/> |

]s can be formed by oxiation of the analogous ] salts. These and also ] are useful as ]s for a various types of ]s. |
