Difference between a solution and a suspension

A solution is a mixture in which other substances (solutes) are dissolved.

• 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

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
