80 examples of homogeneous mixtures and heterogeneous mixtures

The homogeneous and heterogeneous mixtures are different combinations of two or more elements or substances. These mixtures are essential for life on Earth, they can be homogeneous or heterogeneous. Next we will see examples of each of them.

Homogeneous and heterogeneous mixtures

Mixtures are widely used in the daily life of human beings. To achieve a mixture it is necessary to unite two or more substances until a joint matter is formed. Although when joining the components they are mixed, they continue to maintain their chemical properties and can generally be separated again by means of different procedures. A mixture can be made with substances in liquid, solid or gaseous state.

There are two types of mixes:

-Homogeneous : They are those mixtures in which each of the components that have been used in it cannot be differentiated with the naked eye.

– Heterogeneous: They are those mixtures in which if you can see at first you see the different components that have been used since they are usually unevenly distributed.

Difference between homogeneous and heterogeneous mixtures

The main difference between these two types of mixtures (homogeneous and heterogeneous) is the capacity in which the elements or substances that compose them can be differentiated from one another.

In the case of homogeneous mixtures, the elements, substances or components are united in such a way that they are not distinguishable, unlike heterogeneous mixtures where these elements, substances or components can be observed.

Another difference between the two mixtures is in the methods used to separate these mixtures:

In the case of homogeneous mixtures , the main methods for separating their elements or components are:

-Extraction: It is done through polarity.

-Chromatography: it is about the interaction of solutes in different phases.

-Crystallization: It is the use of different temperature, pressure and solubility.

-Evaporation: It consists of the separation using the change from liquid to gaseous state.

-Distillation: Using the different boiling points.

In the case of heterogeneous mixtures, the main methods for separating their elements are:

-Filtration: Through this method solids are separated from liquids.

-Screening: Sifting consists of passing a mixture of particles of different sizes through a sieve or sieve. The smaller particles will pass through the pores of the sieve, passing through it and the large ones will be retained by it. For example sand is separated from silt.

-Centrifugation: Performed by means of centrifugal force.

-Imantation: It consists of the separation of metals from solids or liquids.

-Decantation: It is the division of sediments by the force of gravity. Although at a certain moment the liquids in the mixture may seem mixed, if we let them settle they settle out
, this means that they are arranged in layers according to the order of density.Homogeneous mixtures

Homogeneous mixtures are known as those mixtures where their components cannot be differentiated with the naked eye. The types of homogeneous mixtures in the liquid state are known as solutions and are made up of a solute and a solvent . The most predominant component in the mixture is the solute and the least abundant is the solvent.

Usually in solutions, the liquid or solvent is usually water and the solute can be another liquid or a solid that is dissolved when it is thrown into the solvent.

Examples of homogeneous mixtures

Heterogeneous mixtures

The heterogeneous mixtures are those that are composed of solids, liquids, gases or combinations among them. In general, these combinations are produced by mechanical mixing procedures, by means of which great changes are not generated in the substances used in the mixture. Although these different substances maintain their identities, they can give rise to suspensions, colloids, alloys and other mixtures that will not be very easy to separate.
