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 ...
It is a colourless gas that reacts with oxygen to give water and iodine. Although it is useful in iodination reactions in the laboratory, it does not have large-scale industrial uses, unlike the other hydrogen halides. Commercially, it is usually made by reacting iodine with hydrogen sulfide or hydrazine: [4] 2 I 2 + N 2 H 4 4 HI + N 2
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.
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/100 ml), unless shown otherwise. The substances are listed in alphabetical order.
Iodine bromide may refer to: Iodine monobromide, IBr; Iodine tribromide, IBr 3 This page was last edited on 24 May 2023, at 18:10 (UTC). Text is available under the ...
A test for the presence of iodide ions is the formation of yellow precipitates of these compounds upon treatment of a solution of silver nitrate or lead(II) nitrate. [2] Aqueous solutions of iodide salts dissolve iodine better than pure water. This effect is due to the formation of the triiodide ion, which is brown: I − + I 2 ⇌ I − 3
The first two compounds may also be produced in water – astatine reacts with iodine/iodide solution to form AtI, whereas AtBr requires (aside from astatine) an iodine/iodine monobromide/bromide solution. The excess of iodides or bromides may lead to AtBr − 2 and AtI − 2 ions, [4] or in a chloride solution, they may produce species like ...
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. A representative reagent is Ioversol (Figure to right), [8] which has water-solubilizing diol ...
