The main use of sodium iodate in everyday life is in iodised salt. The other compounds which are used in iodised table salt are potassium iodate, potassium iodide, and sodium iodide. Sodium iodate comprises 15 to 50 mg per kilogram of applicable salt. Sodium iodate is also used as a dough conditioner to strengthen the dough.
Sodium iodide (chemical formula NaI) is an ionic compound formed from the chemical reaction of sodium metal and iodine. Under standard conditions, it is a white, water-soluble solid comprising a 1:1 mix of sodium cations (Na + ) and iodide anions (I − ) in a crystal lattice .
The halogens form many binary, diamagnetic interhalogen compounds with stoichiometries XY, XY 3, XY 5, and XY 7 (where X is heavier than Y), and iodine is no exception. Iodine forms all three possible diatomic interhalogens, a trifluoride and trichloride, as well as a pentafluoride and, exceptionally among the halogens, a heptafluoride.
An iodate is the polyatomic anion with the formula IO − 3. It is the most common form of iodine in nature, as it comprises the major iodine-containing ores. [ 1 ] Iodate salts are often colorless.
Four inorganic compounds are used as iodide sources, depending on the producer: potassium iodate, potassium iodide, sodium iodate, and sodium iodide. Any of these compounds supplies the body with the iodine required for the biosynthesis of thyroxine (T 4) and triiodothyronine (T 3) hormones by the thyroid gland.
Diiodomethane can be prepared from the widely available solvent dichloromethane by the action of sodium iodide in acetone in the Finkelstein reaction: [6] CH 2 Cl 2 + 2 NaI → CH 2 I 2 + 2 NaCl. It can also be prepared by reducing iodoform with elemental phosphorus [7] or sodium arsenite: [6] CHI 3 + Na 3 AsO 3 + NaOH → CH 2 I 2 + NaI + Na 3 ...

Potassium periodate decomposes at 582 °C to form potassium iodate and oxygen. The low solubility of KIO 4 makes it useful for the determination of potassium [citation needed] and cerium. [2] It is slightly soluble in water (one of the less soluble of potassium salts, owing to a large anion), giving rise to a solution that is slightly alkaline.
