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.
The compound is stable on a temperature up to approximately 580 °C (1,076 °F). If the temperature is higher than that value, the following reaction, known as Rammelsberg 's reaction, occurs: [ 3 ] 5 Ba(IO 3 ) 2 → Ba 5 (IO 6 ) 2 + 9 O 2 + 4 I 2
Periodic tables usually at least show the elements' symbols; many also provide supplementary information about the elements, either via colour-coding or as data in the cells. The above table shows the names and atomic numbers of the elements, and also their blocks, natural occurrences and standard atomic weights. For the short-lived elements ...
[2] HIO 3 + NH 3 → NH 4 IO 3. Using its low solubility in water, it can also be precipitated from an iodate solution with an ammonium salt. 2 KIO 3 + (NH 4) 2 SO 4 → 2 NH 4 IO 3 + K 2 SO 4. Unlike other iodates, ammonium iodate can't be prepared by dissolving iodine in an ammonium hydroxide solution, instead the highly explosive nitrogen ...
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

Tin(IV) iodate is an inorganic compound with the chemical formula Sn(IO 3) 4. It was first obtained in 2020 through the hydrothermal reaction of tin(II) oxide and iodic acid in water at 220 °C. [1] It is a colorless columnar crystal, crystallized in the triclinic P 1 space group. [1] It has an indirect band gap (experimental 4.0 eV; calculated ...
