3.12 g/cm 3 This method of delivering potassium iodide does not require a method to weigh out the potassium iodide so it can be used in an emergency situation. Potassium iodide and silver nitrate are used to make silver(I) iodide, which is used for high speed photographic film and for cloud-seeding: KI serves as a source of iodide in organic synthesis. Potassium iodide and anti thyroid medications are also used to prepare the thyroid gland for surgical removal, to treat other overactive thyroid disorders (hyperthyroidism), and to protect the thyroid in an emergency of radiation exposure. On the other hand, iodine is also a chemical element with the symbol (I) which has atomic number 53. Calcium iodide (chemical formula CaI 2) is the ionic compound of calcium and iodine.This colourless deliquescent solid is a salt that is highly soluble in water. Identification Name Potassium Iodide Accession Number DB06715 Description. Bioaccumulative potential Potassium Iodate -Iodide, 0.0125N (0.002083M) [7] [8], Potassium iodide has been used medically since at least 1820. Bedford, MA: CIS-US, Inc. July 1999. Air will oxidize iodide, as evidenced by the observation of a purple extract when aged samples of KI are rinsed with dichloromethane. Recommended Use: Potassium Iodide is an inorganic halogenated salt that is used inpolymer industry in improving structural properties 1-2. 12.3. This effect is due to the formation of the triiodide ion, which is brown: I − + I 2 ⇌ I − 3 Redox, including antioxidant properties. We have the list of top Potassium Iodide suppliers, manufacturers, wholesalers and traders with the best price listed from worldwide. Potassium iodide is a metal-halide salt featuring an ionic bond between the potassium cation (K+) and the iodide anion (I–). The use of KI...was credited with permissible iodine content in 97% of the evacuees tested. In all these cases however, despite the risks, the prophylaxis benefits of intervention with iodide, iodate or perchlorate outweigh the serious cancer risk from radioiodine bioaccumulation in regions where radioiodine has sufficiently contaminated the environment. [24], The World Health Organization does not recommend KI prophylaxis for adults over 40 years, unless the radiation dose from inhaled radioiodine is expected to threaten thyroid function, because the KI side effects increase with age and may exceed the KI protective effects; "...unless doses to the thyroid from inhalation rise to levels threatening thyroid function, that is of the order of about 5 Gy. Washington DC: American Pharmacists Association; 2004. [citation needed] Although the two forms of potassium iodide are completely interchangeable, normally in practice the SSKI solution, which is the historical medical form of high dose iodine, is generally used for all medical purposes save for radioiodine prophylaxis. Aged and impure samples are yellow because of the slow oxidation of the salt to potassium carbonate and elemental iodine.[32]. Iobenguane Sulfate I 131 Injection Diagnostic package insert. The boiling point and melting point of the compound are 1,330 0 C and 681 0 C respectively.

OSHA Vacated PELs: Potassium iodide: No OSHA Vacated PELs are listed for this chemical. Potassium iodide is an inorganic chemical compound which is denoted by the chemical formula KI. Identification Name Potassium Iodide Accession Number DB06715 Description. Researchers at the World Health Organization accurately located and counted the cancer victims from Chernobyl and were startled to find that "the increase in incidence [of thyroid cancer] has been documented up to 500 km from the accident site... significant doses from radioactive iodine can occur hundreds of kilometers from the site, beyond emergency planning zones. Belongs to the Following Reactive Group (s) Potassium iodide is a weak reducing agent, and may react with strong or weak oxidizing agents.
