Hydrogen iodide (HI) is a diatomic molecule and hydrogen halide. Aqueous solutions of HI are known as hydroiodic acid or hydriodic acid, a strong acid.Hydrogen iodide and hydroiodic acid are, however, different in that the former is a gas under standard conditions, whereas the other is an aqueous solution of the gas.

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.
It is an aqueous solution of hydrogen iodide with the chemical formula H I. It is a strong acid, in which hydrogen iodide is ionized completely in an aqueous solution. Concentrated aqueous solutions of hydrogen iodide are usually 48% to 57% HI by mass. [2] An oxidized solution of hydriodic acid.
Hydrogen iodide. The simplest compound of iodine is hydrogen iodide, HI.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.
Iodide hydrides are mixed anion compounds containing hydride and iodide anions. Many iodide hydrides are cluster compounds , containing a hydrogen atom in a core, surrounded by a layer of metal atoms, encased in a shell of iodide.
[contradictory] It oxidizes hydrogen sulfide to sulfur and mustard gas to yield a harmless crystalline sulfimide. [5] It converts iodide to iodine monochloride (ICl). ICl rapidly undergoes electrophilic substitution predominantly with activated aromatic rings, such as those of the amino acid tyrosine. Thus, chloramine-T is used to incorporate ...
Hypervalent organoiodine compounds are prepared by the oxidation of an organyl iodide. In 1886, German chemist Conrad Willgerodt prepared the first hypervalent iodine compound, iodobenzene dichloride (Ph I Cl 2), by passing chlorine gas through iodobenzene in a cooled solution of chloroform: [3] Ph I + Cl 2 → PhICl 2
