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 ...
Approved by the World Health Organization for radiation protection, potassium iodate (KIO 3) is an alternative to potassium iodide (KI), which has poor shelf life in hot and humid climates. [10] The UK , Singapore , United Arab Emirates , and the U.S. states Idaho and Utah all maintain potassium iodate tablets towards this end.
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 ...
This iodine oxide is the anhydride of iodic acid, and one of the few iodine oxides that is stable. It is produced by dehydrating iodic acid at 200 °C in a stream of dry air: [1] 2HIO 3 → I 2 O 5 + H 2 O
Potassium iodate, KIO 3, like potassium iodide, has been issued as a prophylaxis against radioiodine absorption in some countries. [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 ...
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]
IF 5 reacts vigorously with water forming hydrofluoric acid and iodic acid: IF 5 + 3 H 2 O → HIO 3 + 5 HF. Upon treatment with fluorine, it converts to iodine heptafluoride: [6] IF 5 + F 2 → IF 7. It has been used as a solvent for handling metal fluorides.
Periodic acid: Periodic acid Or per-iodic acid, is pronounced / ˌ p ɜːr aɪ ˈ ɒ d ɪ k / PURR-eye-OD-ik and not * / ˌ p ɪər i ˈ ɒ d ɪ k / PEER-ee-OD-ik. It refers to one of two interconvertible species: HIO 4 (metaperiodic acid), or H 5 IO 6 (orthoperiodic acid – illustrated at right).
