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 ...
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 −).
[4] [5] It is also one of the iodine compounds used to make iodized salt. [6] Potassium hydrogen iodate (or potassium biiodate), KH(IO 3) 2, is a double salt of potassium iodate and iodic acid, as well as an acid itself. When some oxygen is replaced by fluorine, fluoroiodates are produced.
Hydrogen iodide (HI) is a diatomic molecule and hydrogen halide. Aqueous solutions of HI are known as hydroiodic acid or hydriodic acid, a strong acid.Hydrogen iodide and hydroiodic acid are, however, different in that the former is a gas under standard conditions, whereas the other is an aqueous solution of the gas.
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. The chemistry of these compounds is complicated with only a few having been well ...
Periodate (/ p ə ˈ r aɪ. ə d eɪ t / pə-RY-ə-dayt) is an anion composed of iodine and oxygen.It is one of a number of oxyanions of iodine and is the highest in the series, with iodine existing in oxidation state +7.
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 ...
Ammonium iodate can be obtained by neutralising a solution of iodic acid with ammonia. [2] HIO 3 + NH 3 → NH 4 IO 3. Using its low solubility in water, it can also be precipitated from an iodate solution with an ammonium salt. 2 KIO 3 + (NH 4) 2 SO 4 → 2 NH 4 IO 3 + K 2 SO 4
