A mixture is a mixture of two or more substances when each of them has its own identification and properties. The resulting mixture may be solid, liquid or gaseous. First of all, the mixture can be homogeneous or heterogeneous. A homogeneous mixture has a uniform composition of atoms or molecules while a heterogeneous mixture has a heterogeneous composition throughout the mixture.
The illustration above shows that a homogeneous mixture has an even distribution of substance atoms throughout the mixture. On the other hand, a heterogeneous mixture has different layers of atoms that can usually be physically separated.
Outline

What is a homogeneous mixture?
The word "homo" comes from the Greek "homos" meaning "the same". A homogeneous mixture consists of particles evenly distributed throughout the mass. The best example of a homogeneous mixture is a solution of sugar and water. When sugar dissolves in water, the sugar molecules are evenly distributed between the water molecules. Both are in the liquid phase and cannot be physically separated.
Homogeneous mixtures can be separated by evaporation, chromatography and distillation processes.
Examples of homogeneous mixtures
- Air is the best example of a homogeneous mixture.
- Natural gas is a mixture of many gases used as fuel.
- Alloys are a mixture of two or more metals containing one phase, such as brass, steel, bronze, silver, etc.
- A chemical solution of similar phases is a homogeneous mixture. e.g. a solution of sugar in water.
- Chemicals used in everyday life, such as dishwashing liquid, vinegar, etc.
- Salt water is a homogeneous mixture until the salt concentration increases the solubility limit.
- Coffee and tea are good examples of homogeneous blends.
- Breathable air analogs such as heliox, nitrox, etc.
- Seawater is a good example of homogeneous mixtures as far as dissolved gases are concerned.
- Perfumes are also homogeneous mixtures.
- All perfect solutions are considered homogeneous mixtures.
What is a heterogeneous mixture?
The word "hetero" comes from the Greek "heterogenès" or means "other". Heterogeneous mixtures are mixtures with a heterogeneous composition of atoms or molecules throughout the mixture. These mixtures always have separate phases that do not mix with each other. The space between two such phases is called interphase.
Interface is an important chemical term denoting the presence of both types of individual phases in some region of space where all properties are fundamentally different from their surroundings. It is an important parameter of heterogeneity of heterogeneous mixtures.
The components of heterogeneous mixtures differ significantly chemically, so physical separation is usually seen due to the force of gravity. The heavier item is pulled down while the lighter one stays up. An example of such a heterogeneous mixture iswater and oilitp.
The individual components of heterogeneous mixtures can be separated by hand harvesting, filtration, sedimentation, distillation, magnetic separation, threshing, sieving, separators, etc.
Examples of heterogeneous mixtures
- Earth's atmosphere is a heterogeneous mixture because the components of the atmosphere are not evenly distributed.
- Mixing two solids results in a heterogeneous mixture such as sand and water, vegetables such as salad, etc.
- Combination of two different phases such as salt and oil, water insoluble crystals are examples of heterogeneous mixtures unless there is adequate dissolution in any way.
- All immiscible liquids form inhomogeneous mixtures, such as oil and water, etc.
- Blood is an example of a heterogeneous mixture containing both solid and liquid components.
- The mixture of bitumen and asphalt is heterogeneous.
- Soil and sand are mixtures of different types of materials, so they are also heterogeneous.
- Drug syrups and solutions are usually mixtures of multi-phase ingredients. This is the reason why the "shake before use" policy is recommended.
- All suspensions and colloids are considered heterogeneous mixtures.

FAQs
What is the difference between homogeneous and heterogeneous mixtures answer? ›
Scientifically speaking, a homogeneous mixture is one in which different parts (such as salt and water) have been uniformly combined into a new substance (salt water), while a heterogeneous mixture has parts that remain separate.
What key factors helped you tell the difference between homogeneous and heterogeneous? ›A homogeneous mixture has a uniform composition and appearance. Individual substances that constitute a homogeneous mixture cannot be visually differentiated. On the other hand, a heterogeneous mixture comprises two or more substances that can be distinctly observed, and even separated relatively easily.
What are the points of differences between homogeneous and heterogeneous mixtures 5? ›- They have consistent compositions. They are not uniform in composition.
- Physically, the components of homogenous mixes are not separate. Physically dissimilar components make up a heterogeneous combination.
- There are no discernible boundaries between the elements. They have distinct borders between the elements.
Heterogeneous refers to a structure with dissimilar components or elements, appearing irregular or variegated. For example, a dermoid cyst has heterogeneous attenuation on CT. It is the antonym for homogeneous, meaning a structure with similar components. Heterogenous refers to a structure having a foreign origin.
