This is an accepted version of this page This is the latest accepted revision, reviewed on 4 February 2025. This article is about the chemical element. For other uses, see Iodine (disambiguation). Chemical element with atomic number 53 (I) Iodine, 53 I Iodine Pronunciation / ˈ aɪ ə d aɪ n, - d ɪ n, - d iː n / (EYE -ə-dyne, -din, -deen) Appearance lustrous metallic gray solid ...
Iodine monofluoride (IF) is unstable at room temperature and disproportionates very readily and irreversibly to iodine and iodine pentafluoride, and thus cannot be obtained pure. It can be synthesised from the reaction of iodine with fluorine gas in trichlorofluoromethane at −45 °C, with iodine trifluoride in trichlorofluoromethane at −78 ...
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 + .
This application exploits the X-ray absorbing ability of the heavy iodine nucleus. A variety of agents are available commercially, many are derivatives of 1,3,5-triiodobenzene and contain about 50% by weight iodine. For most applications, the agent must be highly soluble in water and, of course, non-toxic and readily excreted.
Povidone-iodine is a chemical complex of povidone, hydrogen iodide, and elemental iodine. [4] The recommended strength solution contains 10% Povidone, with total iodine species equaling 10,000 ppm or 1% total titratable iodine. [4] It works by releasing iodine which results in the death of a range of microorganisms. [1]
Tincture of iodine: iodine in ethanol, or iodine and sodium iodide in a mixture of ethanol and water. Lugol's iodine: iodine and iodide in water alone, forming mostly triiodide. Unlike tincture of iodine, Lugol's iodine has a minimised amount of the free iodine (I 2) component. Iodine glycerin, a preparation used in dentistry.
It is a chocolate-brown solid that decomposes at 0 °C, [1] disproportionating to elemental iodine and iodine pentafluoride: 5 IF → 2 I 2 + IF 5. However, its molecular properties can still be precisely determined by spectroscopy: the iodine-fluorine distance is 190.9 pm and the I−F bond dissociation energy is around 277 kJ mol −1.
The role of iodine in mammary tissue is related to fetal and neonatal development, but its role in the other tissues is not well known. [8] It has been shown to act as an antioxidant [8] and antiproliferant [9] in various tissues that can uptake iodine. Molecular iodine (I 2) has been shown to have a suppressive effect on benign and cancerous ...
