potassium iodide ionic compound

[4] Potassium iodide has the chemical formula KI. 9 years ago. 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. Chronic overexposure can have adverse effects on the thyroid.

A sodium atom transfers an electron to a chlorine atom to form a sodium ion and a chloride ion. NaCl, Ag 2 S, PbO) and 2. compounds containing … > Potassium is in Group 1 of the Periodic Table. Centers for decease control and prevention |, McCance; Huether. Required fields are marked *. Definition. VIEW PRODUCT. Plumbous Nitrate [Pb(NO3)2] Lead Nitrate. BBC - GCSE Bitesize: Dot-and-cross diagrams of ionic compounds Diagram of bonding in sodium A sodium ion (2,8)+ pin. Air will oxidize iodide, as evidenced by the observation of a purple extract when aged samples of KI are rinsed with dichloromethane. Recognizing Compounds With Ionic Bonds . In 1945, millions of Japanese were exposed to radiation from nuclear weapons, and the effects can still be measured. Two intermediate compounds have been identified. [18] Iodine-131 iobenguane used for therapeutic purposes requires a different pre-medication duration, beginning 24–48 hours prior to iobenguane injection and continuing 10–15 days following injection. As a supplement, KI exists in tablet or liquid form. Favorite Answer . Why is potassium iodide electrically neutral? In a small study on human subjects, who for each of their 90-day trial, ingested four 20 milligram tetraglycine hydroperiodide (TGHP) water tablets, with each tablet releasing 8 milligrams (ppm) of free titratable iodine;[29] it was found that the biological uptake of radioactive iodine in these human subjects dropped to, and remained at, a value of less than 2% the radioiodine uptake rate of that observed in control subjects who went fully exposed to radioiodine without treatment.[30]. Aqueous KI3, "Lugol's solution", is used as a disinfectant and as an etchant for gold surfaces. Potassium iodide is a metal-halide salt featuring an ionic bond between the potassium cation (K+) and the iodide anion (I–). 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. [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. It is one of the most effective and safe medicines required in a health system and is in the list of the World Health Organization’s List of Essential Medicines. Washington DC: American Pharmacists Association; 2004. Potassium Iodide. Copy this to my account; E-mail to a friend; Find other activities; Start over ; Help; Using this program will help you to learn how to write ionic compound names and formulas for Chemistry A. [10] Potassium iodide is available as a generic medication and over the counter. Elsievier Publishing, US Food and Drug Administration, FDA Talk Paper: Guidance on Protection Against Thyroid Cancer in Case of a Nuclear Accident, US Nuclear Regulatory Commission, Assessment of the Use of Potassium Iodide (KI) As a Public Protective Action During Severe Reactor Accidents Quoting Thyroid Cancer in Children of Belarus Following the Chernobyl Accident, NUREG-1633, United Nations: Office for the Coordination of Humanitarian Affairs (OCHA), Chernobyl, a Continuing Catastrophe, New York and Geneva, 2000, World Health Organization's List of Essential Medicines, https://www.fda.gov/regulatory-information/search-fda-guidance-documents/potassium-iodide-thyroid-blocking-agent-radiation-emergencies, "43-2035 AdreView Panel PI 091908:Layout 1", https://web.archive.org/web/20111007202042/https://www.eanm.org/scientific_info/guidelines/gl_radio_ther_benzyl.pdf?PHPSESSID=46d05b62d235c36a12166bf939b656c7, "Guidelines for Iodine Prophylaxis following Nuclear Accidents", "Potassium Iodide as a Thyroid Blocking Agent in Radiation Emergencies", https://www.cdc.gov/nceh/radiation/emergencies/ki.htm, "POTASSIUM IODIDE - ORAL (SSKI) side effects, medical uses, and drug interactions", "Iodide as a Fluorescence Quencher and Promoter—Mechanisms and Possible Implications", Ullmann's Encyclopedia of Industrial Chemistry, "Iodide prophylaxis in Poland after the chernobyl reactor accident: Benefits and risks", "Vegetables near stricken plant test high for radiation", six questions about a half of million iodine pills, "REQUEST FOR INFORMATION:CRITICAL FOREIGN DEPENDENCIES", "Potassium Iodide Dosage Guidelines & Frequently Asked Questions", "Potassium Iodide: An Antidote for Radiation Exposure", "Oral potassium iodide for the treatment of sporotrichosis", "Successful therapy of refractory erythema nodosum associated with Crohn's disease using potassium iodide", World Health Organization's guidelines for iodine prophylaxis following a nuclear accident, Airborne radioactive particulate monitoring, https://en.wikipedia.org/w/index.php?title=Potassium_iodide&oldid=998383668, World Health Organization essential medicines, Wikipedia articles needing page number citations from May 2012, Articles with dead external links from July 2020, Chemical articles with unknown parameter in Infobox drug, Articles containing unverified chemical infoboxes, Articles with unsourced statements from April 2013, Articles with unsourced statements from August 2020, Articles with unsourced statements from October 2011, Wikipedia medicine articles ready to translate, Creative Commons Attribution-ShareAlike License, iOSAT, SSKI, ThyroSafe, ThyroShield, others, Saturated solutions of potassium iodide can be an emergency treatment for, Iodide solutions made from a few drops of SSKI added to drinks have also been used as, Potassium iodide has been used for symptomatic treatment of. Until drinking, the solution is normally applied to the tea, fruit juice or milk. Typically, when the electronegativity difference in a bond is between 0.5 and 1.7, the compound is formed by a polar covalent bond. Potassium iodide behaves as a simple ionic salt, K + I −.Since the iodide ion is a mild reducing agent, I − is easily oxidised to I 2 by powerful oxidising agents such as chlorine: . However, for several fluorophores addition of KI in μM-mM concentrations results in increase of fluorescence intensity, and iodide acts as fluorescence enhancer.[31].

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. Naval air crew members flying within 70 nautical miles of the Fukushima Daiichi Nuclear Power Plant damaged in the earthquake (8.9/9.0 magnitude) and ensuing tsunami on March 11, 2011. 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. Lead(II) nitrate reacts with potassium iodide in solution to produce the spectator species potassium nitrate, and a bright-yellow lead(II) iodide precipitate. [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. "Pathophysiology: The biological basis for disease in Adults and Children". 2nd ed. 3 Chemical and Physical Properties Expand this section. It is used as an expectorant to break up the mucus so the patient can breathe easily. For reasons noted above, therapeutic drops of SSKI, or 130 mg tablets of KI as used for nuclear fission accidents, are not used as nutritional supplements, since an SSKI drop or nuclear-emergency tablet provides 300 to 700 times more iodine than the daily adult nutritional requirement. U.S. Food and Drug Administration-approved dosing of potassium iodide for this purpose with iobenguane, is as follows (per 24 hours): infants less than 1 month old, 16 mg; children 1 month to 3 years, 32 mg; children 3 years to 18 years, 65 mg; adults 130 mg.[14] However, some sources recommend alternative dosing regimens. Noting that KI's effectiveness was "virtually complete" and finding that iodine in the form of KI was substantially superior to other forms including iodate (KIO3) in terms of safety, effectiveness, lack of side effects, and speed of onset, the FDA invited manufacturers to submit applications to produce and market KI. Ionic bonding is a type of chemical bond that involves the electrostatic attraction between oppositely charged ions, and is the primary interaction occurring in ionic compounds. Ionic Compound Naming and Formula Writing List 1. Potassium iodide is a metal-halide salt featuring an ionic bond between the potassium cation (K+) and the iodide anion (I–). What does mbs adj on a bank statement mean? However, KI administration 96 h or more before 131I exposure has no significant protective effect. Such radiation doses will not occur far away from an accident site. Like other iodide salts, KI forms I3− when combined with elemental iodine. 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. [9] Some of the earliest uses included for syphilis.[9]. [32] It is a white salt, which is the most commercially significant iodide compound, with approximately 37,000 tons produced in 1985. pre-prepared solution formula, made by adding KI to water to prepare a solution containing 1000 mg KI per mL solution (100% wt/volume KI solution), to closely approximate the concentration of SSKI made by saturation.
