Dissolution comes from latin dissolute. The term refers to the action and effect of dissolve (separate what was attached in some way, homogeneously mix the molecules of a substance in a liquid).
The dissolution or solution , therefore, is the resulting homogeneous mixture after dissolving any substance in a liquid. In a solution, it is possible to distinguish between solute (the substance that dissolves in the mixture and that usually appears in smaller quantities) and the solvent or solvent (the substance where the solute dissolves).
It is known as concentration of the solution to the ratio between the amount of solute and the amount of solvent. A higher proportion of dissolved solute, higher concentration, and vice versa.
Within the field of physics and chemistry, it is worth noting the fact that we find a wide variety of types of solutions. Thus, for example, we run into what is called watery. It receives this name because in it the solvent is water.
In the same way, we could talk about what is known as colloidal solution, which develops primarily within the chemical field. It is basically a compound that is the fruit of having carried out the dissolution of a colloid (system formed by two or more phases) in what would be a given fluid.
And we must not forget one of the most frequent solutions. We are referring to the one known as solid, which is the one that takes place as a result of having achieved a homogeneous mixture from two or more substances.
Likewise, if the criteria we consider to classify the solutions is the quality and quantity of the concentration, we would have two other major classifications: the empirical ones and the valued ones.
The first are those in which what is taken into account is the quality of both the solvent and the solute. In this way, they include saturated, supersaturated, concentrated, unsaturated ...
The second, meanwhile, are the ones that oppose the previous ones. That is, they do take into account the amount of solute and solvent that exists. This gives rise to two types: molar solutions and percentage.
It should be noted that a dissolution is not the same as a suspension ; In the latter case, it is a mixture in which the solute is not completely dissolved, but can be found dispersed in small particles.
Salt dissolved in water is an example of dissolution, where salt acts as a solute and water takes on the role of solvent. The dissolution of alcohol in water is another example.
The dissolution, on the other hand, allows naming the breakage or relaxation of the links between several people : "Alcoholism, like any other addiction, can cause the dissolution of a family", “Injustice and inequality can lead the country to its dissolution”, "The dissolution of society is a latent threat to these levels of violence".
