Examples of Hydracids

We explain that what are examples of hydracids? The hydrazides are chemical compounds that form when the combined hydrogen (H) with the elements of VIA VIIA and groups. These are the families of oxygen and halogens , respectively. Hydrogen works with valence +1 by joining with these elements, compensating for their negative valences. They are characterized by the ease with which hydrogen atoms are released when they come into contact with another chemical substance. examples of hydracids

Its molecules are ionic, so when dissolved in water they dissociate into their hydrogen ions H + and that of the non-metal that accompanies it. This explains their high reactivity and the force with which they attack the reactants they face. Hydracids are the strongest acids , followed by oxyacids and finally by organic acids. They reduce the pH of a solution to values ​​between 1 and 5. They are the fastest counteracting the action of strong bases such as hydroxides.

Nomenclature of hydracids examples of hydracids

Hydracids can be named in two ways:

  1. The word “acid” is written, followed by the name of the non-metal, with the ending “-hydric”
  2. It is written as the name of binary salt, writing the nonmetal ending with “uro”, followed by “hydrogen”.

For example, for HCl: examples of hydracids

  1. Hydrochloric acid
  2. Hydrogen chloride

For example, for H 2 S:

  1. Hydrogen sulfide
  2. Hydrogen sulfide

For example, for HBr:

  1. Hydrobromic acid
  2. Hydrogen bromide

For example, for H 2 Se:

  1. Selenhydric acid
  2. Hydrogen selenide

For example, for HI:

  1. Hydroiodic acid
  2. Hydrogen iodide

The two names are correct, but each one has its reason for being:

  1. They are named as acid when they are in aqueous solution , because their ions are in action.
  2. They are named as the hydrogen salt when they are in their pure or concentrated state , which is gaseous.examples of hydracids

Hydracids of the VIA group

The hydracids of group VIA are the following:examples of hydracids

  • Hydrogen sulfide H 2 S
  • Hydrogen selenide H 2 Se
  • Hydrogen telluride H 2 Te

The most important is sulfur H 2 S, which occurs naturally in the decomposition of sulfur compounds. It is the one that says goodbye in the rotting of the egg and leaves an unpleasant and very penetrating smell.

Hydracids of halogens

The hydro acids of the halogens are the following:examples of hydracids

  • Hydrogen Fluoride HF
  • Hydrogen Chloride HCl
  • Hydrogen bromide HBr
  • Hydrogen Iodide HI

Among them, the most used is HCl chloride, which has a high oxidizing power when it is pure and also dissolved in water. In a very low concentration, it becomes a dilute solution that we call muriatic acid , used in cleaning tiles and bathrooms.examples of hydracids

On the other hand, there is also a hydracid that does not come from these two groups, but is the combination of hydrogen with the cyanide radical (CN  ): hydrocyanic acid or hydrogen cyanide (HCN). examples of hydracids
