[edit | edit source]

Iodites (including iodous acid) are highly unstable and have been observed[1] but never isolated.[citation needed] They will rapidly disproportionate to molecular iodine and iodates.[2] However, they have been detected as intermediates in the conversion between iodide and iodate.[3][4]

Other oxyanions

[edit | edit source]

Iodine can assume oxidation states of −1, +1, +3, +5, or +7. A number of neutral iodine oxides are also known.
