Although they do have a certain relationship, these terms cannot be used as synonyms, since each one is a physical procedure, which does not alter the chemical components of the elements, but which have particular characteristics that differentiate them.
What is a Mix?
A mixture is a material that is formed from the union between two or more elements that, without altering their chemical composition, however there are materials that can react against the components of another material or due to environmental conditions, For example, iron oxide occurs when oxygen in the air reacts with iron naturally.
The mixtures can be given by the combination between two elements of the same state, be it liquid, solid or gaseous, or of different states, thus originating different compounds among which are the solutions, in case the liquids predominate; alloys, if there are metallic elements; suspensions, arising from the union of a solid with liquid or gas; or colloids, if fine solids are found in a liquid.
Similarly, the mixtures produced can be classified into two homogeneous and heterogeneous, depending on how the elements that compose it are integrated. Homogeneous mixtures are those that, when combined, form a uniform mass in which it is impossible to identify the materials used with the naked eye, such as in a cake, butter, egg, sugar, milk, flour are placed, but only the ponqué in its final result, also when taking a sample from any part of it, it will be representative of the whole.
On the other hand, in heterogeneous mixtures it is possible to differentiate at a glance how it is composed, since its elements cannot be integrated, so they can be easily separated, and if we take a sample it will be unequal to any other. This happens in salads, for example, because we add potatoes, carrots, beets and onions, sometimes having them all together in each bite, but in others only one or two of the ingredients.
It is possible to separate the mixtures using physical procedures according to the materials used, which can be of the mechanical type such as decantation, filtration, centrifugation and sieving; or thermal among which are evaporation, crystallization, distillation, extraction.
What is a Solution?
A solution is a type of homogeneous mixture in which two or more substances are combined that, when joined, combine in such a way that they form a new substance that is impossible to distinguish with the naked eye. Solutions can be in any of the three states of matter, solid, liquid and gas, but must be made up of two fundamental parts, which are the solute and the solvent.
In a solution, the solute is the element that dissolves and the solvent is the substance that dissolves the solute. The solute usually comes in smaller amounts than the solvent, which makes it easier to form the solution. An example of this could be water with sugar, water being the solvent and sugar the solute, with the action of stirring the sugar it breaks down becoming part of the sugar water.
There are three types of chemical solutions, which are grouped according to the degree of solubility that the solute has by the action of the solvent and are the following:
- Dilute solutions : are those in which there is a low amount of solute with respect to the solvent.
- Concentrated solutions : the amount of solute and solvent is similar, the amount of solvent being only slightly greater.
- Saturated solutions : the solvent is not enough to dissolve the solute, so it is necessary to resort to increasing the temperature or pressure to reach the solution.
It is possible to separate the solution through procedures such as evaporation, distillation, liquefaction. In another order of ideas, the solution is also known as dissolution, so according to the context the term may vary, or it has been a synonym of it.
Difference Between Mixture and Solution
- A mixture results from the union of two or more elements without causing a chemical reaction. There are two types of mixture: heterogeneous and homogeneous. While the solution is a kind of homogeneous mixture.
- In mixtures, substances maintain their chemical properties, unlike solutions, where sometimes the new substance has properties different from those of its components.
- If the mixture is heterogeneous, the parts that compose it can be differentiated with the naked eye. The opposite case of the solution, which because it is homogeneous, it is not possible to differentiate the elements that were present before mixing.
- The types of mixture are homogeneous and heterogeneous. For its part, the solution is classified as diluted, concentrated and saturated.
