Potassium iodate may be used to protect against accumulation of radioactive iodine in the thyroid by saturating the body with a stable source of iodine prior to exposure. [9] 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 ...
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 ...
Potassium iodide is a component in the electrolyte of dye sensitised solar cells (DSSC) along with iodine. Potassium iodide finds its most important applications in organic synthesis mainly in the preparation of aryl iodides in the Sandmeyer reaction, starting from aryl amines. Aryl iodides are in turn used to attach aryl groups to other ...
Percentage of share of households consuming iodized salt. Edible salt can be iodised by spraying it with a potassium iodate or potassium iodide solution. 57 grams of potassium iodate, costing about US$1.15 (in 2006), is required to iodise a ton (2,000 pounds) of salt. [1]
An alternative protocol uses a solution of iodate ion (for instance potassium iodate) to which an acidified solution (again with sulfuric acid) of sodium bisulfite is added. [3] 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
For this reason, people at risk of exposure to environmental radioactive iodine (iodine-131) in fallout may be instructed to take non-radioactive potassium iodide tablets. The typical adult dose is one 130 mg tablet per 24 hours, supplying 100 mg (100,000 micrograms ) of ionic iodine (the typical daily dose of iodine for normal health is on the ...
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.
