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.
In this protocol, iodide ion is generated by the following slow reaction between the iodate and bisulfite: IO − 3 + 3 HSO − 3 → I − + 3 HSO − 4. This first step is the rate determining step. Next, the iodate in excess will oxidize the iodide generated above to form iodine: IO − 3 + 5 I − + 6 H + → 3 I 2 + 3 H 2 O
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.

Because ammonium iodate consists of the reducing ammonium ion and the oxidizing iodate ion, it already starts to decompose at 150 °C into nitrogen, oxygen, iodine and water. NH 4 IO 3 → 1 / 2 N 2 + 1 / 2 O 2 + 1 / 2 I 2 + 2H 2 O
Potassium iodate (K I O 3) is an ionic inorganic compound with the formula KIO 3. It is a white salt that is soluble in water. It is a white salt that is soluble in water. [ 1 ]
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.
Ionic iodides MI n tend to have the lowest melting and boiling points among the halides MX n of the same element, because the electrostatic forces of attraction between the cations and anions are weakest for the large iodide anion. In contrast, covalent iodides tend to instead have the highest melting and boiling points among the halides of the ...
