Iodite is an anion composed of iodine and oxygen, with the chemical formula IO2−. Within this ion the iodine exists in oxidation state III.
Iodites (including iodous acid) are highly unstable and have never been isolated.[1] However they have been detected as intermediates in the conversion between iodide and iodate.[2][3]
Other oxyanions
Iodine can assume oxidation states of −1, +1, +3, +5, or +7. A number of neutral iodine oxides are also known.
