# Mixtures, Solutions and Suspensions

### Mixtures

A mixture is a combination of substances which are not chemically joined together.

• Mixtures have the same properties as their components
• There is no fixed proportion between the components
• The components can be separated from the mixture

#### Examples

• sugar and salt
• air with nitrogen and oxygen

### Solutions

A solution is a homogeneous mixture in which one substance (solute) is dissolved in another substance (solvent).

• The components in a solution may not be separated from the solution by leaving it to stand, or by filtration

If a material dissolves in a liquid the material is said to be soluble. A solution is saturated if no more solute can be dissolved with temperature remaining constant.

#### Examples

• salt in sea water

### Suspensions

A suspension is a mixture of liquids with particles of a solid which may not dissolve in the liquid.

• The solid may be separated from the liquid by leaving it to stand, or by filtration

#### Examples

• sand in water
