A solution is an example of a homogeneous mixture.


In chemistry, a mixture is a material made up of two or more different substances that are mixed, but not combined chemically i.e. the separate components maintain their individual identity. Mixtures can either be homogeneous or heterogeneous.

Homogeneous mixtures have the same uniform appearance and composition throughout. A solution is an example of a homogeneous mixture - made up of a solute dissolved in a solvent e.g. salt dissolved in water.

Heterogeneous mixtures have two components that are separate from one another because they are a) in different phases e.g. sand (solid) and water (liquid), or b) immiscible e.g. oil and water. These mixtures are often called 'suspensions'.

Some mixtures can have heterogeneous and homogeneous character e.g. 'colloid' mixtures, in which fine particles are suspended in solution. Visually, it looks like a solution (homogeneous), but if you look microscopically, you can see that the particles are only suspended (heterogeneous) and not dissolved.
