    en.wikipedia.org/wiki/Hypoiodous_acid

    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 −).

    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 ...

    en.wikipedia.org/wiki/Iodic_acid

    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 ...

    Iodine pentoxide (I 2 O 5). Iodine oxides are chemical compounds of oxygen and iodine.Iodine has only two stable oxides which are isolatable in bulk, iodine tetroxide and iodine pentoxide, but a number of other oxides are formed in trace quantities or have been hypothesized to exist.

    en.wikipedia.org/wiki/Hydroiodic_acid

    Hydroiodic acid (or hydriodic acid) is a colorless liquid. It is an aqueous solution of hydrogen iodide with the chemical formula H I. It is a strong acid, in which hydrogen iodide is ionized completely in an aqueous solution. Concentrated aqueous solutions of hydrogen iodide are usually 48% to 57% HI by mass. [2] An oxidized solution of ...

    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.

  9. Iodous acid - Wikipedia

    en.wikipedia.org/wiki/Iodous_acid

    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 .
