In general, There are physical and chemical components. Briefly, Mixtures and Compounds are two or more elements and substances that combine together forms chemically and physically.
Meaning of Mixtures:
A mixture is a material made up of two or more different substances which are not chemically combined.
Example:
- Dirt and water(mud)
- Sand, water and gravel (cement)
- Oxygen and water (seafoam)
Meaning of Compounds:

Difference Between Mixtures and Compounds:
| Mixtures | Compounds |
|---|---|
| Meaning | |
| Elements or compounds just mix together to form a mixture and no new compound is formed. | Elements react to form new compounds. |
| Composition | |
| A mixture is a variable composition. | The composition of each new substance is always fixed. |
| Properties | |
| A mixture shows the properties of the constituent substances. | The new substance has totally different properties. |
| Constituents | |
| The constituents can be separated fairly easily by physical methods. | The constituents can be separated only by chemical or electrochemical reactions. |
| Characteristics | |
| They don't show their own characteristics. | They show their own characteristics. |
| Ratio | |
| The ratio of mixture components can vary. | Present in a fixed ratio. |
Bottom line:
As a result of the preceding discussion, Mixtures are variable composition and Compounds are of each substance are always fixed. They have their own properties, characteristics, constituents, and ratio.
