Liquid iodine trichloride conducts electricity, possibly indicating dissociation to ICl + 2 and ICl − 4 ions. [9] Iodine pentafluoride (IF 5), a colourless, volatile liquid, is the most thermodynamically stable iodine fluoride, and can be made by reacting iodine with fluorine gas at room temperature. It is a fluorinating agent, but is mild ...

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 monobromide is an interhalogen compound with the formula IBr. It is a dark red solid that melts near room temperature. [1] Like iodine monochloride, IBr is used in some types of iodometry. It serves as a source of I +. Its Lewis acid properties are compared with those of ICl and I 2 in the ECW model. It can form CT adducts with Lewis ...
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 + .
It can be made from the elements at low temperature, or from iodine pentoxide and hydrogen chloride. It reacts with many metal chlorides to form tetrachloroiodides (ICl − 4), and hydrolyses in water. The molecule is a planar dimer (ICl 3) 2, with each iodine atom surrounded by four chlorine atoms. Iodine tribromide (IBr 3) is a dark brown liquid.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Tungsten(III) iodide is a black solid that releases iodine at room temperature, and is less stable than molybdenum(III) iodide. It is soluble in acetone and nitrobenzene, and slightly soluble in chloroform. [1] It decomposes to form tungsten(II) iodide: [1] [] +
The name "aluminium iodide" is widely assumed to describe the triiodide or its dimer. In fact, a monoiodide also enjoys a role in the Al–I system, although the compound AlI is unstable at room temperature relative to the triiodide: [7] 3 AlI → AlI 3 + 2 Al
