When discussing the concept of solution, defined as the homgéneo system containing a solvent and dissolved in one or more solutes. Generally, the major component is the solvent and solute minority.
There are different types of solutions depending on the amount of solute dissolved. When a small amount of dissolved solute is a dilute solution. If the amount of solute is increased talk of a concentrated solution. If the amount grows we call saturated solution. Here is the solubility limit. That is, more solute is not supported. If the amount is exceeded we have a supersaturated solution. The excess of undissolved solute precipitate.

Moreover there are several types of solutions depending on the physical state of its components.
Perhaps the most common are those formed by a solvent liquid and a solid solute. There are also formed by liquid – liquid, liquid – gas, since many gases are dissolved in liquid. Air is an example of a solution consisting of gaseous oxygen, nitrogen and others.
Others are solids in solids, such as alloys.
The degree of solubility of solutes in solvents such as salts or hydroxides in water is seriously affected by factors such as temperature. An increase in temperature increases
