What are oxysalts?


In order to fully understand wat oxysalts are , it is necessary to understand the chemical concept of salt. This is a type of compound that is formed thanks to the bond that occurs between cations and anions , a process that generates a reaction from the acid and the base . Oxysalts are basically a type of salt and are born when the combination between an oxacid acid and a hydroxide is made , in other words between a metal and a radical . The result of this combination is what is known in the area of ​​chemistry as oxisal , oxosal oroxacid salt , names by which it is also known.

What are oxysalts?

The oxysalts are a number of chemical compounds which are formed by a metal and radical which contains oxygen. They are the product that results from the neutralization reaction that occurs between a certain oxyacid and a base.

Characteristics of oxisales

Its main features include the following:

  • They can be found in the form of rocks mainly when they are located in underground deposits .
  • It can be crushed or pulverized to achieve a better use.
  • They have the ability to dissociate when mixed with water .
  • When in an aqueous solution then they have the ability to conduct the electricity .
  • Its internal structure is crystalline .
  • They can produce hydrates .
  • Their melting points are quite high but also at medium temperatures they can be fused.
  • They are soluble in water forming aqueous solutions.
  • All the particles that make up an oxisal have a certain level of order and are also compact , thus being able to form crystals.
  • When they are in humid environments they can form hydrates.

Types of oxysalts

The types of oxysalts that exist are the following:

  • Acidic : they are formed by the union of hydrogen and an atom of a non-metallic element except oxygen. In order to know if it is an acid oxysalt then the formula must have an intermediate hydrogen located between the metal and the nonmetal.
  • Neutral : they are all oxysalts in which the hydrogens in the acid have been replaced by a hydroxide metal. If the presence of intermediate elements between the metallic element and the non-metallic element is not present in the chemical formula , then it will be neutral.
  • Basic : in this case, they can be formed when the hydroxide from which it comes has a greater amount of OH- and when they have not been fully substituted. To know if it is basic then in the formula there must be an OH group located between the metallic element and the non-metallic element.


Its formulation, in other words, the nomenclature of oxisal, follows a series of rules that involve situations such as the following:

  • When the metal has only one valence : when the metal of the oxisal has only one valence, then the name of the radical , the word ” of ” and finally the name of the metal must be placed . The nomenclature can also be given by placing the name of the radical followed by the name of the metal with the ending ” ico “.
  • When the metal has several valences : in this case, a nomenclature must be given by placing the radical name , the word “ of ”, the name of the metal and finally the valence of the metal placed in Roman numerals . Another way is by placing the name of the radical plus the name of the metal and adding to this last point, the ending depending on the valence “bear” or “ico”.

In this way, there are several types of nomenclature, which are:

  • Traditional nomenclature that is made using the name of the oxoacid element and that consists of substituting the ending ” bear ” for ito or ” ico ” for aco . Subsequently, the name corresponding to the metallic element must be added by adding the ending depending on the valence, ico if it has valence 1 or bear if it has valence 2.
  • Systematic nomenclature where the name is given starting with the name of the anion , the name of the cation and the prefix that corresponds to the number of atoms that the metallic element has.
  • Nomenclature in stock that is quite similar to the traditional one and that rigorously requires the use of the metallic element and the valence which must also be placed within a parenthesis.

How they are formed

Oxysalts are made up of a metal, a nonmetal, and oxygen molecules. Its formula is a (X b O c ) n ,

where M is the metallic element , X is the non-metallic element and finally O is the oxygen . The letters a, b, c are the origin values ​​of the oxoacid and the letter n represents the valence that the metallic element possesses.

What are oxisales for?

Oxysalts have a large number of uses, all of them important but they stand out in the pharmacological , industrial and practical fields . Many can be found naturally in the crust of the earth. They are compounds widely used in the field of chemistry and laboratories as well as in the agricultural industry because they act perfectly well as direct fertilizers in the soil. They also participate as a residual product in the manufacture of some materials such as nylon . Some of them, such as magnesium phosphate, are used as medicinal products mainly to combat muscle pain, menstrual pain and contractures.

Many are also used to cause the sedimentation of residues in water tanks that have not been subjected to the purification process and some are even used as water purifiers , in treatments against anemia and to increase iron levels in food. Sodium hypochlorite is an oxisal widely used mainly as a kind of bactericide and disinfectant , to treat sewage and to whiten surfaces and clothes.

They are also used as calcium supplements, in the production of glass , cement , as an antacid and coagulant . Hydrogen peroxide needs oxysal barium sulfate to be formulated, as well as it is necessary in X-ray rooms because it has opacity to radiation.


Oxysalts are products of great importance especially for industry, society and even the health in general of human beings. They are necessary to be able to maintain, preserve and preserve food and for a series of technological and environmental processes.


Some well known examples of oxysalts are mentioned below:

  • Potassium nitrate : its chemical formula is KNO 3 and it is one of the main ingredients used to manufacture gunpowder and other types of explosives.
  • Calcium sulfate : also known by the name of gypsum, it is a compound that is added to mixtures made with concrete or cement to be later placed on floors and walls.
  • Calcium carbonate . Its formula is CaCO3 and it is commonly known by the name of limestone.
  • Sodium sulfate : it can be extracted from the subsoil and is generally used as an ingredient in detergents.
  • Sodium hypochlorite: its formula is NaCIO and is used in dilute aqueous solutions, for example in disinfectants that are made and sold to clean bathrooms.
