Heterogeneous mixture is a combination of two or more distinct substances which can be separated through mechanical means. Read on to know more about heterogeneous mixtures and its examples.

Examples Of Heterogeneous Mixtures

The examples of heterogeneous mixtures are found in substances in our natural surroundings. In simpler terms, they are a combination of two or more distinct substances and the components which form these mixtures are visible to the naked eye and are easily distinguishable. For example, in beach sand, you can easily distinguish beach and sand as they are large enough to be visible to a human eye. The examples of heterogeneous mixtures constitute liquids, gases and solids which we find in our day to day life. Though, in technical terms, even homogenous mixtures are heterogeneous, they are regarded homogeneous as the components forming them are too small to be visible to the human eye. Heterogeneous mixtures, in turn, are easily spotted and can be physically separated. We find plenty of heterogeneous mixtures examples around us in the form of chocolate chip cookies, granite, oil and vinegar, a tossed salad, pizza and a bowl of raisin, different types of cereals and so on.

Heterogeneous Mixture
Mixture – Homogenous And Heterogeneous
A mixture is a combination of substances that are not proportionate to each other and not chemically united.  We see mixtures in all the natural substances and they are made of components which can be physically separated and are easily distinguishable from one another. Mixtures are homogenous and heterogeneous. Homogeneous mixtures are a combination of equally proportionate substances which possess identical characteristics. As the components melt at varied temperatures, the mixture does not display a specific melting point. Sugar solution is an example of homogeneous mixture where the sugar crystals cannot be separated from the sugar solution by mechanical means. To do that, sugar solution must be boiled so that water is evaporated and the sugar crystals are left behind.
Heterogeneous mixtures are a combination of substances which lack a uniform composition and do not have identical characteristics. An example is sand and iron fillings which can be separated through mechanical means such as sifting or filtration.
Examples Of Heterogeneous Mixtures
Suspensions comprise of huge liquid particles and insoluble solid particles. Unlike homogenous ones, heterogeneous mixtures do not require a medium to distinguish the substances with which they are made of. They are seen scattered around in liquid, though they settle in no time, and can be picked out easily with the human eye. Those solid particles can be physically separated via filtration method using filter paper and centrifugation. In beach sand, a physical eye can easily make out the unique small pebbles. Another example of suspensions is clay in water or sand in water.
Emulsion is a type of suspension where the mixture constitutes of two liquids which are mixed together. These two liquids do not blend well when mixed, however hard you try to do so by shaking and/or stirring. If you leave them undisturbed for a specific period of time, they settle in two different layers one above the other. The examples of emulsions are water and kerosene or oil and water.
An atom is an example of heterogeneous mixture as it contains different components such as protons, electrons and neurons. These components are held together by bonds which are not chemical in nature and can be broken with the help of certain processes.
Common Examples
Sand And Sugar
Sand and sugar is an example of heterogeneous mixture as the grains in it are easily distinguishable under a magnifying glass. You can separate the sugar grains and the sand grains in it by washing the sugar out with water.
Iced Tea With Cubes Of Ice
Iced tea with visible cubes of ice is an example of heterogeneous mixture as the compositions and properties which make up belong to different phases and are distinguishable. However, iced tea without the ice cubes becomes a homogenous mixture. Iced tea is heterogeneous only till you can see ice cubes floating in it. The moment the ice cubes melt, iced tea goes back to being homogenous.
Other Examples Of Heterogeneous Mixtures
  • Beach sand is an example of heterogeneous mixture as the varied coloured particles in it can be viewed and separated.
  • Vinegar and oil salad dressing is an example of heterogeneous mixtures as two solid and liquid layers are present in it and the distinction is quite obvious.
  • Air with clouds, as is found over cities, is an example of heterogeneous mixtures as it constitutes dust, smoke, microorganisms, water, water vapour, fuel exhausts, etc.
  • Smoke is an example of heterogeneous mixture as it is the mixture of substances in more than one phase. It is the mixture of solid, liquid and gaseous components.
  • The other examples of heterogeneous mixtures are sandwich, salads, sand in water, soil, rocks, atmosphere, carbonated soft drinks, chicken soup, red wine vinegar, vinegar in oil, concrete, wood,chocolate chip cookies, muddy water, orange juice with pulp, lentil soup, sugar and cornstarch, mixture of different types of cereals, paving cement, etc.
The aforementioned details are of mixtures that are not completely blend together and the components making them can be separated by various physical means. They are formed of uneven substances which cannot be combined.
