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 ...
Orthoperiodic acid, H 5 IO 6, is stable, and dehydrates at 100 °C in a vacuum to metaperiodic acid, HIO 4. Attempting to go further does not result in the nonexistent iodine heptoxide (I 2 O 7), but rather iodine pentoxide and oxygen. Periodic acid may be protonated by sulfuric acid to give the I(OH) + 6 cation, isoelectronic to Te(OH) 6 and ...
More autocatalysis when newly generated iodous acid also converts chlorate in the fastest reaction step: ClO − 3 + HIO 2 → IO − 3 + HClO 2 In this clock the induction period is the time it takes for the autocatalytic process to start after which the concentration of free iodine falls rapidly as observed by UV–visible spectroscopy .

A hypohalous acid is an oxyacid consisting of a hydroxyl group single-bonded to any halogen. Examples include hypofluorous acid, hypochlorous acid, hypobromous acid, and hypoiodous acid. The conjugate base is a hypohalite. They can be formed by reacting the corresponding diatomic halogen molecule (F 2, Cl 2, Br 2, I 2) with water in the reaction:
Diiodine oxide, also known as iodo hypoiodite, is an oxide of iodine that is equivalent to an acid anhydride of hypoiodous acid. This substance is unstable and it is very difficult to isolate. This substance is unstable and it is very difficult to isolate.
