This is an accepted version of this page This is the latest accepted revision, reviewed on 25 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 ...
By the same token, however, since iodine has the lowest ionisation energy among the halogens and is the most easily oxidised of them, it has a more significant cationic chemistry and its higher oxidation states are rather more stable than those of bromine and chlorine, for example in iodine heptafluoride. [1]
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]
Iodine is a chemical element with many uses in medicine, depending on the form. Elemental iodine and iodophors are topical antiseptics. [2] Iodine, in non-elemental form, functions as an essential nutrient in human biology (see iodine in biology). [3] Organic compounds containing iodine are also useful iodinated contrast agents in X-ray imaging ...
The "2% free iodine" description is based on the quantity of elemental iodine, not sodium/potassium iodide. [citation needed] USP Strong Iodine Tincture is defined in the NF as containing in each 100 mL, 6.8 to 7.5 gram of iodine, and 4.7 to 5.5 gram of potassium iodide. Purified water is 50 mL and the balance is alcohol.
The use of Iodine-131 as a poison – used in small doses over a period of time to disrupt a person's ability to think and tell right from wrong – played a central role in the episode "The Case of the Melancholy Marksman" of the long-running CBS TV series Perry Mason (season 5, episode 24, first broadcast March 24, 1962).
Medical use of iodine compounds (i.e. as a contrast agent) can cause anaphylactic shock in highly sensitive patients, presumably due to sensitivity to the chemical carrier. Cases of sensitivity to iodine compounds should not be formally classified as iodine allergies, as this perpetuates the erroneous belief that it is the iodine to which ...
In iodane chemistry, carbon is considered more electronegative than iodine, despite the Pauling electronegativities of those respective atoms. [2] Thus iodobenzene (C 6 H 5 I) is an iodine(I) compound, (dichloroiodo)benzene (C 6 H 5 ICl 2) and iodosobenzene (C 6 H 5 IO) iodine(III) compounds, and iodoxybenzene (C 6 H 5 IO 2) an iodine(V) compound.
