mix definition

The combination of two or more substances is known as a mixture, without a chemical reaction occurring as a consequence of this and the substances participating in the aforementioned mixture will retain their properties and identity..

Meanwhile, what can differ are the chemical properties of the different components and, in general, according to the cases and needs, they can be separated, that is, their components isolated, through various mechanical procedures.

A common example of mixing is that of sand with iron filings, which, at first glance, it is easy to verify that both continue to maintain their properties.

There are two types of mixtures, homogeneous mixtures and heterogeneous mixtures.

Homogeneous are those that are produced when two or more pure substances are joined in variable proportions, which will maintain their original properties as is and can be separated through physical or mechanical procedures. In homogeneous ones, one cannot see its components with the naked eye, not even using an electron microscope will it be possible to distinguish the parts, since in any of its parts the mixture will present the same composition. They will be known as solutions, once the mixture has been produced, the solute being in a lower proportion than the solvent.

Among the homogeneous, five basic mixtures are recognized: solid-solid, liquid-solid, liquid-liquid, gas-liquid and gas-gas.

Meanwhile and contrary to the previous ones, heterogeneous mixtures are those that have a non-uniform composition, that is, they are made up of two or more physically different phases and arranged in an absolutely uneven manner. In what if they coincide with the previous ones, it is that each of the parts of a heterogeneous composition can be separated from each other through mechanical procedures. Wood, granite, oil and water, among others, are examples of heterogeneous mixtures.

On the other hand, with the term mixture, in addition to the question that we explained above, we can refer to any kind of alteration in the traditional order of things or to the combination of things that are totally different from each otherAs an example of this we can mention those musical groups that certainly claim to be the product of two or more musical currents such as rock or jazz, among others.
