Hydrazic acid
The hydrogen form compounds with other chemical elements hydrogenated binary. Examples of these we have hydrogen chloride, HCl The binary compounds of groups VI A and VIIA of the Periodic Table are gaseous molecular substances at room temperature and pressure, the bonds that bind Hydrogen and the other non-metallic element are polar covalent and its polar molecules. The [Hydrogen] acts with oxidation number +1, and they are the only binary hydrogen compounds where hydrogen is formulated on the left.
Hydrogen + X ——— HX; Hydrazides
To name these compounds, valences are interchanged, using both the traditional nomenclature and the stock nomenclature. In the Stock nomenclature, the suffix uro is added to the nonmetal root followed by “Hydrogen”. In the traditional nomenclature, they are named as “Acid, the root of non-metal and ending in Hydric”. Examples:
| Formula | Stock | Traditional |
| H2S | Hydrogen sulfide | Hydrogen Sulfide |
| HF | Hydrogen Fluoride | Hydrofluoric acid |
| H2Se | Hydrogen Selenide | Hydrogen Selenic Acid |
| HCl | Hydrogen chloride | Hydrochloric acid |
Hydrazic Salts or Binary Salts: They are compounds formed by the combination of a non-metal (the same as for binary acids and with the same oxidation state) and a metal. They have only traditional nomenclature and in this, to the root of the non-metal is added the ending uro followed by “de” and the name of the metal with its oxidation state in parentheses and in Roman numerals. If the element has only one oxidation state, it is not written. Examples:
| Formula | Name |
| NaI | Sodium iodide |
| CsCl | Cesium chloride |
| Bat | Barium TELENIDE |
| FeS | Iron (II) Sulfide |
Properties
- Non-metallic hydrazids are gaseous substances at room temperature.
- They are soluble in water.
- Hydrazides in solution conduct the electric current .
Chemical nomenclature and notation
The non-metal ending in “uro” is named followed by “de” and the word “hydrogen”
These compounds are called hydracids due to the property that upon dissolving in water they give acid solutions, that is, they yield hydrogen easily. This circumstance is noted with the subscript (ac) that indicates aqueous solution. In this case it is named with the word ” acid”and the name of the non-metal terminated in -hydric. Non-metal-hydric acid If they give us the formula In the formula: The non-metal terminated in” -uro “is named. In the formula: If they are in aqueous solution it is named as “acid” and the name of the nonmetal ending in -hydric. If you give us the name In the name: The number of hydrogens matches the oxidation number of the nonmetal. In the name: The number of hydrogens matches the number of oxidation of the non-metal Examples Within this group we can also formulate the HCN that has an acid hydrogen linked to the cyanide group that contains a triple bond It is named as hydrogen cyanide, but in solution it will be hydrocyanic acid.
Uses of hydracids
Hydryacids are currently of great importance in the Chemical Industry , since almost all the elements used to make personal hygiene products are present. For example, in soaps, they play a fundamental role. Of course, they do not come in high concentrations, they are subjected to a filtering process to lower the concentration of hydrogen, an element that poses a great risk to the human body if we are exposed to large amounts of it. Hydracids are also present in shampoos, in dental pastes, in hair conditioners, in cosmetics, in short, in all personal hygiene, beauty and makeup accessories, the use of these compounds is essential, hence their great importance for the development of industries. They are also used in some foods.
