[12] Potassium iodate (KIO3) is used to add iodine to some salts so that the iodine is not lost by oxidation. Does not form Crystalline hydrates. Bromine trifluoride rapidly attacks potassium iodide [Mellor 2, Supp. white (1) Feature. [15][17], Product labeling for diagnostic iodine-131 iobenguane recommends potassium iodide administration one day before injection and continuing 5 to 7 days following administration, in keeping with the much longer half-life of this isotope and its greater danger to the thyroid. It is conventionally rounded to 50 mg per drop. Iodine-potassium iodide. Boiling point of Potassium is 760°C. 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. Ice(solid water) Hope this helps! Find chemicals information Potassium iodide at guidechem, professional and easy to use.

Recession or inhibition of thyroid function can lead to excessive secretion of TSH and even goiter. KI is also used as a fluorescence quenching agent in biomedical research, an application that takes advantage of collisional quenching of fluorescent substances by the iodide ion. Find chemicals information Potassium iodide at guidechem, professional and easy to use. [15], Not all sources are in agreement on the necessary duration of thyroid blockade, although agreement appears to have been reached about the necessity of blockade for both scintigraphic and therapeutic applications of iobenguane. 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. [22] A likely lethal dose of salt (more than a kilogram[23]) would be needed to equal the potassium iodide in one tablet. Properties of potassium iodide KI: White, when stored on the light turn yellow. Stop taking medicine to subside. 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. The boiling point of potassium iodide is 1,330 degrees Celsius.That would be 2,426 degrees Fahrenheit. 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 . Potassium iodide cannot protect against any other mechanisms of radiation poisoning, nor can it provide any degree of protection against dirty bombs that produce radionuclides other than those of iodine. ... M. "Potassium iodide, but not potassium iodate, as a potential protective agent against oxidative damage to membrane lipids in porcine thyroid." "[20], The U.S. Department of Health and Human Services restated these two years later as "The downward KI (potassium iodide) dose adjustment by age group, based on body size considerations, adheres to the principle of minimum effective dose. [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. Potassium iodide is a white crystalline solid that looks and tastes like table salt (NaCl), dissolves in water, has a melting point of 631 o C, and a boiling point of 1330 o C. It's used, along with sodium iodide … November 13, 2020 Uncategorized Uncategorized Potassium iodide, 1 kg, glass ≥99,5 %, p.a., ISO. Potassium iodide (K(I3)) T66M6Y3KSA. Kowalsky RJ, Falen, SW. Radiopharmaceuticals in Nuclear Pharmacy and Nuclear Medicine. Potassium iodide is a chemical compound, medication, and dietary supplement. Potassium iodide is a chemical compound, medication, and dietary supplement. what type of reaction is Na2B4O7.10H2O + 2HCl -> 2NaCl(aq) + 5H2O + 4B(OH)3. Potassium iodide is a component in the electrolyte of dye sensitised solar cells (DSSC) along with iodine. As a medication it is used to treat hyperthyroidism, in radiation emergencies, and to protect the thyroid gland when certain types of radiopharmaceuticals are used. 7790-42-3. Melting point. DTXSID90228534. Free samples program. Potassium and sodium Iodide are used in photography and as analytical reagents. [citation needed], KI is used with silver nitrate to make silver iodide (AgI), an important chemical in film photography. Guidechem provides Potassium iodide chemical database query, including CAS registy number 7681-11-0, Potassium iodide MSDS (Material Safety Data Sheet), nature, English name, manufacturer, function/use, molecular weight, density, boiling point, melting point, structural formula, etc. In accordance with the column 2 of Annex VII of the REACH regulation, this end point can be considered for waiver since the melting point is above 300 C. However, there is data which indicates that the vapour pressure of potassium iodide is 133.322 Pascal at temperature of 745oC. 0 0. 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 . [2] [3] As a medication it is used to treat hyperthyroidism, in radiation emergencies, and to protect the thyroid gland when certain types of radiopharmaceuticals are used. How long will the footprints on the moon last? KI is a component in some disinfectants and hair treatment chemicals. In 2017, the Dutch government distributed pills to hundreds of thousands of residents who lived within a certain distance of nuclear power plants and met some other criteria.
