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 ...
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 ...
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 −).
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.
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.
It can be prepared by reacting a potassium-containing base such as potassium hydroxide with iodic acid, for example: [1]. HIO 3 + KOH → KIO 3 + H 2 O. It can also be prepared by adding iodine to a hot, concentrated solution of potassium hydroxide: [1]
It can be prepared by reacting a sodium-containing base such as sodium hydroxide with iodic acid, for example: HIO 3 + NaOH → NaIO 3 + H 2 O. It can also be prepared by adding iodine to a hot, concentrated solution of sodium hydroxide or sodium carbonate: 3 I 2 + 6 NaOH → NaIO 3 + 5 NaI + 3 H 2 O
Diiodine pentoxide (I 2 O 5) is the anhydride of iodic acid and the only stable anhydride of an iodine oxoacid. Tetraiodine nonoxide (I 4 O 9) has been prepared by the gas-phase reaction of I 2 with O 3 but has not been extensively studied. [11]
