Meaning of heterogeneous mixtures
What are Heterogeneous Mixtures:
A heterogeneous mixture is a combination of 2 or more elements or substances (which can occur in any state of matter), in which its components can be identified.
The natural environment in which we live is made up of millions of mixtures, some of which are essential for life.
Blood, for example, is a smorgasbord indispensable to life. Although its elements cannot be distinguished with the naked eye, thanks to the microscope, it can be seen that it is composed of plasma, red blood cells and platelets.
Heterogeneous mixtures in chemistry
In chemistry, heterogeneous mixtures are differentiated from homogeneous mixtures if the components of this are identifiable.
Another way to identify if the mixture is heterogeneous is through the techniques of separation of its components. In heterogeneous mixtures there are the following types of methods:
- Filtration: technique used, for example, in the separation of solid waste from liquids when water is filtered. Gravity or also vacuum filtration is used.
- Sifting: separation of sand from silt used, for example, by pre-Hispanic civilizations to acquire construction materials.
- Centrifugation: separates using centrifugal force such as water from clothes in the washing machine.
- Magnetization: separates iron from other solids, which can be used, for example, to search for coins in the sand.
- Decantation: the elements of the mixture are divided using gravity, for example, when the cream is separated from the milk.

Heterogeneous and homogeneous mixture
Heterogeneous mixtures differ from homogeneous mixtures because the components that form them are identifiable.
Both are types of chemical mixtures, defined as such for the identification of the characteristics and properties of each one. Heterogeneous mixtures, for example, have component separation techniques that differ from homogeneous mixtures.
