USP Tincture of Iodine is defined in the U.S. National Formulary (NF) as containing in each 100 mL, 1.8 to 2.2 grams of elemental iodine, and 2.1 to 2.6 grams of sodium iodide. Alcohol is 50 mL, and the balance is purified water. This "2% free iodine" solution has 0.08 mol/L of I 2, which provides about 1 mg of free iodine per 0.05 mL drop. The ...
Potassium iodate may be used to protect against accumulation of radioactive iodine in the thyroid by saturating the body with a stable source of iodine prior to exposure. [9] Approved by the World Health Organization for radiation protection, potassium iodate (KIO 3 ) is an alternative to potassium iodide (KI) , which has poor shelf life in hot ...
The best way to store vitamins for optimal shelf-life Elements like heat, humidity, light, and air are the “main enemies of vitamin freshness,” says Blatner. “Keep them cool, dry, and out of ...
Some analytical procedures exploit the oxidizability of thiosulfate anion by iodine. The reaction produces tetrathionate: 2 S 2 O 2− 3 + I 2 → S 4 O 2− 6 + 2 I −. Due to the quantitative nature of this reaction, as well as because Na 2 S 2 O 3 ·5H 2 O has an excellent shelf-life, it is used as a titrant in iodometry.
Unlike tetraglycine hydroperiodide tablets, iodine crystals have an unlimited shelf life as long as they are not exposed to air for long periods of time or are kept under water. Iodine crystals will sublimate if exposed to air for long periods of time. The large quantity of water that can be purified with iodine crystals at low cost makes this ...
Iodine-131 (usually as iodide) is a component of nuclear fallout, and is particularly dangerous owing to the thyroid gland's propensity to concentrate ingested iodine and retain it for periods longer than this isotope's radiological half-life of eight days. For this reason, people at risk of exposure to environmental radioactive iodine (iodine ...
Lugol's iodine is a liquid made up of two parts potassium iodide for every one part elemental iodine in water. [8] Lugol's iodine was first made in 1829 by the French physician Jean Lugol. [7] [8] It is on the World Health Organization's List of Essential Medicines. [9] [10] Lugol's iodine is available as a generic medication and over the ...
Iodine monochloride is an interhalogen compound with the formula ICl. It is a red-brown chemical compound that melts near room temperature . Because of the difference in the electronegativity of iodine and chlorine , this molecule is highly polar and behaves as a source of I + .
