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.
Silicic acid is the name given to a variety of compounds with a generic formula [SiO x (OH) 4−2x] n. [24] [25] Orthosilicic acid has been identified in very dilute aqueous solution. It is a weak acid with pK a1 = 9.84, pK a2 = 13.2 at 25 °C. It is usually written as H 4 SiO 4, but the formula Si(OH) 4 is generally accepted.
Hydroid (botany), a type of vascular cell that occurs in certain bryophytes; Hydroid (zoology), a life stage for most animals of the class Hydrozoa; Garveia, a genus of cnidarians, including: Garveia annulata, the orange hydroid; Garveia arborea, the orange or hedgehog hydroid
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.

Section through a hydroid. The majority of hydroids are colonial. The original polyp is anchored to a solid substrate and forms a bud which remains attached to its parent. This in turn buds and in this way a stem is formed. The arrangement of polyps and the branching of the stem is characteristic of the species.
Acid strength is the tendency of an acid, symbolised by the chemical formula, to dissociate into a proton, +, and an anion, .The dissociation or ionization of a strong acid in solution is effectively complete, except in its most concentrated solutions.
The hydroxy group is pervasive in chemistry and biochemistry. Many inorganic compounds contain hydroxyl groups, including sulfuric acid, the chemical compound produced on the largest scale industrially. [2] Hydroxy groups participate in the dehydration reactions that link simple biological molecules into long chains.
