The oxisales they constitute a salt class which arises when an oxidic acid and a hydroxide or, more simply, a radical and a metal are combined. The fruit of this link is known as oxisal , oxosal or oxidic salt .

To understand what oxisals are, therefore, we have to know what various concepts refer to. Let's start with the notion chemistry of salt: it is a compound that is formed by linking cations and anions (that is, ions with different charges: positive and negative). The salts, in this way, are the result of a reaction which is generated from the relationship between an acid (the anion) and a base (the cation).

Oxacids and hydroxides form the oxisals. The first compound (also called oxoacid acid) is created from a molecule of H2O (water) and a non-metallic oxide. The hydroxides, on the other hand, are composed of a metal together with one or more hydroxyl anions. The difference between a hydroxide and a oxide It is found that these are formed with oxygen.

In addition, it must be stated that the oxisales formula establishes that both the metallic element and the non-metallic element and oxygen come into play, without forgetting the values ​​of oxoacid and the valence of the first of these, of the metal.

No less important is knowing that there are several nomenclatures for oxisales. However, among the most significant are the following:
• Traditional nomenclature. This is the one that is taken using the name of the oxoacid element and consists in replacing its termination -oso by -ito, or -ico by -aco. To this will be added the name of the metallic element with a termination depending on its valence: -ico if it has 1, -oso if it has 2…
• Systematic nomenclature. In this case, with some exceptions, the name is given in this order: name of the anion + name of the cation + prefix of the number of atoms of the metallic element.
• Nomenclature in stock. This is very similar to the traditional one and also requires the use of the metallic element in question and its valence. The latter must be stated that it must be in parentheses.

It should also be stressed that the oxisales have a number of characteristics that are worth highlighting. Among these are the following: most have the peculiarity that they are soluble in water, they can get to conduct electricity and many of them are used in the field of medicine to prevent botulism or perform X-ray radiographs, for example.

He sodium nitrate , he calcium chlorite and the cobalt silicate They are some examples of oxisales. Its use is very varied: they can be used for cleaning, prevent diseases , produce glass or manufacture dentifrices, among other functions.

It should be noted that the name of the oxisals, with their prefixes and suffixes, obeys various rules that are common in the field of chemistry.
