Potassium iodide has been used as a mucolytic agent. When did organ music become associated with baseball? Description Potassium iodide is a chemical compound, a metal halide composed of potassium and iodide with thyroid protecting and expectorant properties and its formula is KI . Stockroom Favorite (2) Application. iodide melting point. Request For Quotation. Recession or inhibition of thyroid function can lead to excessive secretion of TSH and even goiter. Potassium iodide with KI chemical formula crystallized in a cubic structure.it is a White powder with high solubility in water that can be changed in yellow in the presence of air and light oxygen. Potassium iodide, 1 kg, glass ≥99,5 %, p.a., ISO. Aqueous KI3, "Lugol's solution", is used as a disinfectant and as an etchant for gold surfaces. Unlike I2, I3− salts can be highly water-soluble. Dedicated nutritional iodide tablets containing 0.15 mg (150 micrograms (μg)) of iodide, from KI or from various other sources (such as kelp extract) are marketed as supplements, but they are not to be confused with the much higher pharmaceutical dose preparations. Potassium triiodide (CAS NO.12298-68-9), its Synonyms are Iodine-potassium iodide ; Lugol's iodine ; Lugol's solution ; Microiodide ; Potassium iodide ; Potassium iodide (K(I3)) . Does not form Crystalline hydrates. Melting / freezing point at 101 325 Pa: 685°C. Potassium triiodide. Share . [citation needed]. Cited in 1 publications Within ten years of the accident, it became clear that thyroid damage caused by released radioactive iodine was virtually the only adverse health effect that could be measured.

In 2012, Fleming Co. sold all its product rights and manufacturing facility to other companies and no longer exists. The experimental value of the melting point of potassium iodide by the capillary method was found to be 685°C at an atmospheric pressure of 975hPa . At 20 degrees Celsius the solubility of KI is 140-148 grams per 100 grams of water. [12] Potassium iodate (KIO3) is used to add iodine to some salts so that the iodine is not lost by oxidation. 681° Boiling Point. An aqueous solution of KI chemically dissolves potassium iodide by complexation. Potassium iodide can be conveniently prepared as a saturated solution, abbreviated SSKI. "[21] For optimal prevention, KI must be dosed daily until a risk of significant exposure to radioiodine by either inhalation or ingestion no longer exists. [7] [8], Potassium iodide has been used medically since at least 1820. Note that, these points are associated with the standard atmospheric pressure. [53] Because KI is about 76.4% iodide by weight, SSKI contains about 764 mg iodide per mL. According to one 2000 study "KI administered up to 48 h before 131I exposure can almost completely block thyroid uptake and therefore greatly reduce the thyroid absorbed dose. The key difference between iodine and potassium iodide is that iodine is a chemical element whereas potassium iodide is a chemical compound.. Iodine is a halogen that locates in group 17 of the periodic table of elements.On the other hand, potassium iodide is a chemical compound that forms from the combination of iodine and potassium. 8 years ago. In the event of a radioiodine release the ingestion of prophylaxis potassium iodide, if available, or even iodate, would rightly take precedence over perchlorate administration, and would be the first line of defence in protecting the population from a radioiodine release. For SSKI, a solution more viscous than water, there are assumed to be 15 drops per mL; the iodide dose is therefore approximately 51 mg per drop. Density is given for the actual state at 25°C and for liquid phase at melting point temperature. 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. As reported by the NRC, studies after the accident showed that "As of 1996, except for thyroid cancer, there has been no confirmed increase in the rates of other cancers, including leukemia, among the... public, that have been attributed to releases from the accident. Potassium iodide is a component in the electrolyte of dye sensitised solar cells (DSSC) along with iodine. 13 0. A typical tablet weighs 160 mg, with 130 mg of potassium iodide and 30 mg of excipients, such as binding agents. Iodine aqueous. Through this reaction, iodine is used in redox titrations. Potassium iodide is a chemical compound, medication, and dietary supplement. With pure water, the concentration of KI in the solution depends only on the temperature. is more than that in KCl. 0 0. [51] Potassium iodide may also be administered pharmaceutically for thyroid storm. Properties, SDS, Applications, Price. [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. KI crystals are simply added to water until no more KI will dissolve and instead sits at the bottom of the container. The alkali metal iodide salt, over time and exposure to excess oxygen and carbon dioxide, slowly oxidizes to metal carbonate and elemental iodine, which then evaporates.

Subbaswamy Department of Physics and Astronomy, University of Kentucky, Lexington, KY 40506, USA (Received 22 June 1981 by A. G. Chynoweth) We have measured the Raman spectrum of potassium iodide in the crystalline phase at high temperatures, and in the melt… Lugol's solution. [26], There have been some reports of potassium iodide treatment causing swelling of the parotid gland (one of the three glands that secrete saliva), due to its stimulatory effects on saliva production.[27]. Potassium iodide is an ionic compound which is made of the following ions: K+I−. [3] It is given by mouth. 7790-42-3. UNII-T66M6Y3KSA. US Nuclear Regulatory Commission, Report on the Accident at the Chernobyl Nuclear Power Station, NUREG-1250. Mobility in soil No additional information available 12.5. Potassium Iodide is a metal halide composed of potassium and iodide with thyroid protecting and expectorant properties. KI can turn yellow upon heating in air or upon standing in moist air for long periods, because of oxidation of the iodide to iodine. [44], It was reported on March 16, 2011, that potassium iodide tablets were given preventively to U.S. Potassium iodide (KI) is prepared by reacting potassium hydroxide to iodine with a hot solution. Thus, the spectrum is structurally similar to those found in … Arrange the solids in order of decreasing melting point. They are used in the measurement of the energy of gamma rays, by measuring the amplitude of pulses of light generated by electrons which are excited by the gamma rays. [citation needed] As noted, the equivalent two drops of SSKI (equaling the dose of one KI pill) may be used for this purpose, if the pills are not available. The recommended standard (daily) dose of KI for all school-age children is the same (65 mg). "[43], The development of thyroid cancer among residents in the North Pacific from radioactive fallout following the United States' nuclear weapons testing in the 1950s (on islands nearly 200 miles downwind of the tests) were instrumental in the 1978 decision by the FDA to issue a request for the availability of KI for thyroid protection in the event of a release from a commercial nuclear power plant or weapons-related nuclear incident. white (1) Feature.

Emergency 130 milligrams potassium iodide doses provide 100 mg iodide (the other 30 mg is the potassium in the compound), which is roughly 700 times larger than the normal nutritional need (see recommended dietary allowance) for iodine, which is 150 micrograms (0.15 mg) of iodine (as iodide) per day for an adult. [4], Common side effects include vomiting, diarrhea, abdominal pain, rash, and swelling of the salivary glands. O'Neil. The measures were seen as precautions, and the Pentagon said no U.S. forces have shown signs of radiation poisoning. November 13, 2020 Uncategorized Uncategorized +Add Attachment "[41], But equally important to the question of KI is the fact that radioactivity releases are not "local" events. EINECS 235-567-5. Lugol's solution. [28], The use of a particular 'Iodine tablet' used in portable water purification has also been determined as somewhat effective at reducing radioiodine uptake. As formed under acidic conditions, hydriodic acid (HI) is a stronger reducing agent.[33][34][35]. Saturation, and also in the electrolyte of dye sensitised solar cells ( DSSC ) along iodine.
