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

In the first case, the solution involves the satisfaction of a concern or reason with which a trouble . In the field of literature , he theater or the cinema, the solution is the outcome or the finalization of the argument, which usually resolves any unknowns that the viewer may have according to the plot.

Within that artistic field, we would have to highlight the existence of a film that makes use of the term in question 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.

It tells a real fact: 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 that left 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 to the figure of a series of characters who, for some reasons or others, are destined to let their needs and feelings flow.

Solving something, therefore, is solve it or terminate it . For example: “My house has leaks: I have to find a solution or it will flood”, "Don't worry, let's think together about a solution for your problems", “I don't have a job and tomorrow I finish the house: I need an urgent solution”.

For mathematics, the solution is the possible values ​​of the unknowns of a equation . It is also the function that verifies a differential equation: "If 2 + x = 5, the solution to 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 marketing. Where appropriate, it is used to refer to what a product or service of a particular company is. However, on other occasions when this word is used it is also done to refer to the sum of the two things: the service and the product.

In the field of chemistry , a solution or dissolution 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 solvent .

The relationship between the amount of solute and the amount of solvent is called solution concentration . 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 usually talk about what is the solid solution, which is that homogeneous and solid mixture formed by the union of two substances.
