It is a white salt, which is the most commercially significant iodide compound, with approximately 37,000 tons produced in 1985. However, for several fluorophores addition of KI in μM-mM concentrations results in increase of fluorescence intensity, and iodide acts as fluorescence enhancer.[31]. Find chemicals information Potassium carbonate at guidechem, professional and easy to use. Anonymous. However, adolescents approaching adult size (i.e., >70 kg [154 lbs]) should receive the full adult dose (130 mg) for maximal block of thyroid radioiodine uptake. RE: Arrange the solids in order of decreasing melting point.? CAS No. Delen. MSDS: Chinese USA: Flash Point: 1330°C: Symbol: GHS07: Signal Word: Warning × Can anyone help me solve this chemistry problem. 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. [11] Potassium iodide is also used for the iodization of salt. 77, No. Neither SSKI or KI tablets are used as nutritional supplements, since the nutritional requirement for iodine is only 150 micrograms (0.15 mg) of iodide per day. [citation needed], There is reason for caution with prescribing the ingestion of high doses of potassium iodide and iodate, as their unnecessary use can cause conditions such as the Jod-Basedow phenomena, trigger and/or worsen hyperthyroidism and hypothyroidism, and then cause temporary or even permanent thyroid conditions. All of these doses should be compared with the far lower dose of iodine needed in normal nutrition, which is only 150 μg per day (150 micrograms, not milligrams). Potassium Chloride. Today, nearly half (44.8%) the survivors of Nagasaki studied have identifiable thyroid disease, with an editorial in The Journal of the American Medical Association reporting "it is remarkable that a biological effect from a single brief environmental exposure nearly 60 years in the past is still present and can be detected. Density is given for the actual state at 25°C and for liquid phase at melting point temperature. Iodine aqueous. O'Neil. Free samples program. [53] Because KI is about 76.4% iodide by weight, SSKI contains about 764 mg iodide per mL. "[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. 58 / Monday, March 26, 2012 / Rules and Regulations Revision date: 04/02/2015 04/02/2015 EN (English) 1 SECTION 1: Identification of the substance/mixture 1.1.
