## What Does solution Mean

The term solution , from the Latin solutĭo , has two great uses. On the one hand, it is about the action and effect of solving a difficulty or a doubt. On the other hand, solution is the action and effect of dissolving .

In the first case, the solution supposes the satisfaction of a concern or the reason with which a problem is unlocked . In the field of literature , theater or cinema, the solution is the denouement or ending of the plot, which usually solves any unknown the viewer may have according to the plot.

Within this artistic field, we would have to highlight the existence of a film that uses the term at hand in its title. This is the North American production "The Final Solution," directed by Frank Pierson and starring actors such as Colin Firth, Stanley Tucci and Kenneth Branagh.
In it a true event is narrated: the celebration of the well-known Wannsee Conference. This is a meeting that took place on January 20, 1942 and was made up of fifteen people, different political and military leaders, who created the "Final Solution of the Jewish problem." A document this that laid the foundations of what would be the Nazi holocaust.
Also in the literary field there is the novel "The saline solution." The writer Marco Vassi published in 1996 this story of erotic and sensual content in which we are approached by the figure of a series of characters who, for one reason or another, are doomed to let their needs and feelings flow.
Solving something, therefore, is solving it or ending it . For example: "My house has leaks: I have to find a solution or it will flood" , "Don't worry, we will think together a solution for your problems" , "I don't have a job and tomorrow they will finish off the house: I need one urgent solution ” .
For mathematics, the solution is the possible values ​​of the unknowns of an equation . It is also about the function that verifies a differential equation: "If 2 + x = 5, the solution of the equation is 3 since 2 + 3 = 5" .
In the same way, we cannot ignore the fact that the term solution is also used in the field of marketing. Where appropriate, it is used to refer to what a product or service of a specific company is. However, on other occasions when this word is used it is also used to refer to the sum of the two things: the service and the product.
In chemistry , a solution or solution is a homogeneous mixture of two or more substances . The substance that is usually in smaller quantity and that dissolves in the mixture is known as solute ; the substance where the solute dissolves is called a solvent .

The relationship between the amount of solute and the amount of solvent is called the concentration of the solution . It should be noted that the chemical properties of the components of the substances are not altered in a solution. However, the physical properties of the solution differ from the physical properties of the pure solvent.
In this field, we often talk about what a solid solution is, which is that homogeneous and solid mixture formed by the union of two substances.
