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] 3 I 2 + 6 KOH → KIO 3 + 5 KI + 3 H 2 O
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 ...
Periodic acid (/ ˌ p ɜːr aɪ ˈ ɒ d ɪ k / per-eye-OD-ik) is the highest oxoacid of iodine, in which the iodine exists in oxidation state +7. It can exist in two forms: orthoperiodic acid, with the chemical formula H 5 IO 6, and metaperiodic acid, which has the formula HIO 4. Periodic acid was discovered by Heinrich Gustav Magnus and C. F ...
Iodic acid is most easily made by oxidation of an aqueous iodine suspension by electrolysis or fuming nitric acid. Iodate has the weakest oxidising power of the halates, but reacts the quickest. [14] Many periodates are known, including not only the expected tetrahedral IO − 4, but also square-pyramidal IO 3− 5, octahedral orthoperiodate 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.

Iodine monochloride is soluble in acids such as HF and HCl but reacts with pure water to form HCl, iodine, and iodic acid: ICl + H 2 O → HCl + HI + 1 ⁄ 2 O 2 2 ICl + H 2 O → 2 HCl + I 2 + 1 ⁄ 2 O 2 5 ICl + 3 H 2 O → 5 HCl + HIO 3 + 2 I 2. ICl is a useful reagent in organic synthesis. [2]
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
