Heterogeneous Mixtures with Examples
Completely opposite of homogeneous mixtures, heterogeneous mixtures are two or more substances that are distinct from one another. For example, the physical eye can pick up the substances that make up this type of mixture because they are large enough to be seen. Like homogeneous mixtures, examples of heterogeneous mixtures can include solids, liquids and gases.
Some liquid examples include salad dressing and red wine vinegar. A gas example can include air with clouds in it while a solid examples include beach sand as well as paving cement. Pretty much anything that is not the same throughout can be considered a heterogeneous mixture (think the planet Earth or even human beings).
Another type of heterogeneous mixture is a suspension. Unlike colloids, which need a medium to reveal particular substances, the physical eye can pick out the substances without the need for a medium. For example, beach sand can reveal how it is made up of several small pebbles that are different. Red wine vinegar has the same properties in that you can see the different substances that flow from it.
In conclusion, homogeneous and heterogeneous mixtures are a part of everyday life. Even though homogeneous mixtures are technically heterogeneous mixtures, they are still considered homogeneous because the physical eye cannot see the different substances. Heterogeneous mixture examples, however, are remarkably easy to spot the different substances that make up the composition.
