Examples of Hydracids

Hydrohalic , also known as hydrohalic acids or metal hydrides are chemical compounds that arise from combination of hydrogen atoms with halogen atoms (fluorine, chlorine, bromine or iodine: 6A group of the Periodic Table), or with atoms amphoteric or chalcogenic elements, such as sulfur, selenium or tellurium (group 7A of said table).

The first act with oxidation state +1 and the second with state of oxidation +2 , so in the case of hydracids with halogens the formula that represents them is HX, while the hydracids with amphigens are schematized with the formula H 2 X.

Hydracid characteristics

Hydrates do not contain oxygen . It is clear that the compounds thus formed are binary and acidic in aqueous solutions .

Other non-metals also form binary compounds with hydrogen, but not necessarily acids. For example, ammonia combines nitrogen with hydrogen and when the pH dissolves, it does not decrease.

Hydracids are usually named with both the traditional nomenclature (example: hydrochloric acid) and Stock nomenclature (example: hydrogen chloride).

The hydrogen halides (called so that comprise a halogen directly combination with hydrogen) are strong acids (except hydrogen fluoride), acid strength (based on the ability to release protons dissociate in solution) increases as that the atomic mass is increased, that is, as the periodic table of elements is traversed from top to bottom. Concentrated solutions of these acids usually release white smoke.

Uses of hydro acids

Hydrazides are used today in different chemical industries. Many times they are used to formulate hygiene and household cleaning products. For example, they are important components of soaps, of course at low concentrations.

Hydrazides are also present in toiletries and personal hygiene products , such as shampoos, toothpastes, hair conditioners and certain cosmetics. At higher concentrations, they are used as pipe cleaners.

In order to digest food, our body synthesizes gastric juice , which is released in the stomach. This juice contains various enzymes (pepsin, renin, gastric lipase) and hydrochloric acid, produced by the parietal cells of the aforementioned organ.

This acid causes the pH in the stomach to be around 2, or even somewhat lower. In these conditions the degradation of food is possible.

Hydracid examples

There are only seven hydracids , these are:

  1. Hydrochloric acid HCL )
  2. Hydrogen sulfide (H2S)
  3. Hydrogen bromide (HBr)
  4. Hydrogen selenide (H2Se)
  5. Hydrogen iodide (HI)
  6. Telluric acid (H2Te)
  7. Hydrofluoric acid (HF)
