The terms heterogeneous and homogeneous refer to mixtures of materials in chemistry. The difference between heterogeneous and homogeneous mixtures is the degree at which the materials are mixed together and the uniformity of their composition.

A homogeneous mixture is a mixture where the components that make up the mixture are uniformly distributed throughout the mixture. The composition of the mixture is the same throughout.

There is only phase of matter observed in a homogeneous mixture. So, you wouldn't observe both a liquid and a gas or a liquid and a solid in a homogeneous mixture.

Homogeneous Mixture Examples:

There are several examples of homogeneous mixtures encountered in everyday life:

• Air.
• Sugar water.
• Rain water.
• Vodka.
• Vinegar.
• Dishwashing detergent.
• Steel.

You can't pick out components of a homogeneous mixture or use a simple mechanical means to separate them. You can't see individual chemicals or ingredients in this type of mixture. Only one phase of matter is present in a homogeneous mixture.

A heterogeneous mixture is a mixture where the components of the mixture are not uniform or have localized regions with different properties.

Different samples from the mixture are not identical to each other. There are always two or more phases in a heterogeneous mixture, where you can identify a region with properties that are distinct from those of another region, even if they are the same state of matter (e.g., liquid, solid).

Heterogeneous Mixture Examples

Heterogeneous mixtures are more common than homogeneous mixtures. Examples include:

• Cereal in milk.
• Vegetable soup.
• Pizza.
• Blood.
• Gravel.
• Ice in soda.
• Salad dressing.
• Mixed nuts.
• Bowl of colored candies.
• Soil.
