Iodous acid is the chemical compound with the formula HIO 2. Its salts are named iodites ; these are exceedingly unstable and have been observed but never isolated. [ 1 ] They will rapidly disproportionate to molecular iodine and iodates .
Iodine oxides are chemical compounds of oxygen and iodine. ... Iodous acid: Iodic acid: Periodic acid: Formula HI HIO HIO 2: HIO 3: HIO 4 or H 5 IO 6
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]
Iodous acid and iodite are even less stable and exist only as a fleeting intermediate in the oxidation of iodide to iodate, if at all. [13] Iodates are by far the most important of these compounds, which can be made by oxidising alkali metal iodides with oxygen at 600 °C and high pressure, or by oxidising iodine with chlorates .
Hypoiodous acid is an inorganic compound with the chemical formula H I O. It forms when an aqueous solution of iodine is treated with mercuric or silver salts. It rapidly decomposes by disproportionation: [2] 5 HIO → HIO 3 + 2 I 2 + 2 H 2 O. Hypoiodous acid is a weak acid with a pK a of about 11. The conjugate base is hypoiodite (IO −).
Iodic acid is a white water-soluble solid with the chemical formula HIO 3. Its robustness contrasts with the instability of chloric acid and bromic acid. Iodic acid features iodine in the oxidation state +5 and is one of the most stable oxo-acids of the halogens. When heated, samples dehydrate to give iodine pentoxide. On further heating, the ...

An iodate is the polyatomic anion with the formula IO − 3. It is the most common form of iodine in nature, as it comprises the major iodine-containing ores. [1] Iodate salts are often colorless. They are the salts of iodic acid.
