A heterogeneous mixture Is a mixture which is composed of elements that are non-uniform or have localized regions having different properties.
In physical chemistry and materials science, the definition of a heterogeneous mixture is that of a mixture containing components in distinct phases.
Many common substances are heterogeneous blends; In fact most of the mixtures that are observed in the day to day are heterogenous.
A heterogeneous blend is a blend having a non-uniform composition. The composition varies from one region to another, with at least two phases remaining separated from one another with clearly identifiable properties.
If a sample of a heterogeneous mixture is examined, the separate components can be observed.
In a heterogeneous mixture, the substances are not located in a fixed proportion. Likewise, the substances in the mixtures maintain their individual properties; Unlike the Homogeneous mixtures , The properties of the two substances never change.
Similarly, an important physical property of a heterogeneous mixture is the ability to separate substances through some physical mode. This means that the two substances can be removed without modifying them on a chemical level.

List of 22 examples of heterogeneous substances
1- If you add Sand to a bottle of water , The mixture would simply be a mixture of both sand and water.
At no point, no matter how much sand or how much water is added to the mixture, the mixture as such will change. This is an example of a heterogeneous mixture called suspension, which is a mixture between a liquid and a solid.
2- The soups or Vegetable and meat stock Are heterogeneous mixtures. If a person makes a soup and adds several ingredients, the different ingredients would remain the same despite being mixed inside the soup.
3- The Earth Is a heterogeneous mixture, since if you pick up a handful of soil from the ground you will find that there are several types of plants, sand, and other substances scattered unevenly across the earth.
4- A Cereal bowl with milk Is a heterogeneous mixture. No matter how much you mix, this common snack will always continue to consist of both cereal and milk; They will never be combined in the same substance.
5- The Sand beach Is a heterogeneous mixture as it is composed of several rocks, and even animals, that vary in both size and composition.
6- A Pizza Is heterogeneous. The Toppings, Or added ingredients such as ham or pineapple, are not evenly distributed through the pizza, nor is the cheese and sauce the same. This means that it is a heterogeneous mixture.
7- The Mixtures of nuts Are heterogeneous mixtures because the elements that compose it are different. Each caramel of different color, each nut, or each dried fruit that is part of the mixture and composes it is heterogeneous.
8- The ocean Is one of the largest heterogeneous mixtures in existence. The sea is a non-uniform distribution of animals, plants, and other essential components that make it heterogeneous.
9- The Mixture of oil and water Is a good example of a heterogeneous mixture called emulsion; The oil will never dissolve completely in the water. An emulsion is a heterogeneous mixture that combines two liquids.
10- The pollution Or contamination is a heterogeneous mixture of several particles suspended in the air.
The dirty particles that make up the pollution can be removed from the air and breathed by the lungs, which is why pollution is a heterogeneous mixture harmful to humans.
11- A salad Is a heterogeneous composition. This food contains several separate vegetables, such as lettuce or kale, cheese, seeds, and other components that make it a heterogeneous mixture.
12- A mud puddle Counts as a heterogeneous mixture as it is composed of soil, grass, leaves, and animal waste mixed in the water.
13- The Hollandese sauce Which usually carry the Benedictine eggs does not look like a heterogeneous mixture but it is.
It is a heterogeneous mixture in the form of an emulsion that can be decomposed into its constituent parts (butter, egg yolks and lemon juice).
14- An example of a heterogeneous mixture is also a atom , Since this is a mixture of several parts like protons, electrons and neutrons. As has been demonstrated with nuclear weapons, atoms can be divided using certain methods.
15- Although the Vinegar and oil Are often mixed as a seasoning, the mixture as such is heterogeneous. They can stay together for a while, but they will always separate after a while.
16- The concrete used in construction is a heterogeneous mixture of an aggregate, Cement and water .
17- The ice cubes in a soda or soda form a heterogeneous mixture. He Ice and drink Are distinct phases of matter (solid and liquid)
18- The Chocolate chip cookies E are also a heterogeneous mixture. If a person takes a bite out of the cookie, they may not have the same number of chocolate chips they can get in another bite.
19- The Sodas or soft drinks Are considered heterogeneous mixtures; Contain water, sugar and carbon dioxide that form bubbles.
While sugar, water, and flavorings may form a chemical solution, carbon dioxide bubbles are not evenly distributed throughout the liquid.
20- The Salt and pepper seasonings Form a heterogeneous mixture.
21- The Sugar and sand Also form a heterogeneous mixture. If they are thoroughly mixed and observed, small crystals of sugar and sand particles can be identified separately.
22- A Bottle of balsamic vinegar salad dressing Is a heterogeneous mixture; Must be stirred for the mixture and the flavors appear more combined.
