What is a heterogeneous mixture?

A heterogeneous mixture is a mixture in which the components are not uniformly distributed and can often be seen separately. Different parts of the mixture may have different compositions.

Examples:

• Oil and water

• Sand mixed with water

• Soil

• Vegetable salad

Unlike a homogeneous mixture, a heterogeneous mixture does not have the same composition throughout. Its components usually retain their individual properties and can often be separated by physical methods.
