Hydroiodic acid (or hydriodic acid) is a colorless liquid. 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 ...
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 systematic IUPAC name is not always the preferred IUPAC name, for example, lactic acid is a common, and also the preferred, name for what systematic rules call 2-hydroxypropanoic acid. This list is ordered by the number of carbon atoms in a carboxylic acid.
For example, there is a weak bond between hydrogen and iodine in hydroiodic acid, making it a very strong acid. [ citation needed ] In the simplest case, binary acid names are formed by combining the prefix hydro- , the name of the non-hydrogen nonmetallic element, the suffix -ic , and adding acid as a second word.

In such cases, the H centre has nucleophilic character, which contrasts with the protic character of acids. The hydride anion is very rarely observed. Sodium hydride as an example of hydride salt. Almost all of the elements form binary compounds with hydrogen, the exceptions being He, [2] Ne, [3] Ar, [4] Kr, [5] Pm, Os, Ir, Rn, Fr, and Ra.
Upon dissolution in water, which is highly exothermic, the hydrogen halides give the corresponding acids. These acids are very strong, reflecting their tendency to ionize in aqueous solution yielding hydronium ions (H 3 O +). With the exception of hydrofluoric acid, the hydrogen halides are strong acids, with acid strength increasing down the ...
Representation of an organic compound hydroxy group, where R represents a hydrocarbon or other organic moiety, the red and grey spheres represent oxygen and hydrogen atoms respectively, and the rod-like connections between these, covalent chemical bonds. In chemistry, a hydroxy or hydroxyl group is a functional group with the chemical formula ...
According to the modern definition, a superacid is a medium in which the chemical potential of the proton is higher than in pure sulfuric acid. [2] Commercially available superacids include trifluoromethanesulfonic acid ( CF 3 SO 3 H ), also known as triflic acid, and fluorosulfuric acid ( HSO 3 F ), both of which are about a thousand times ...
