A solution is a specific type of homogeneous mixture.

Components: A solute (substance dissolved) in a solvent (dissolving medium).
Separation: Cannot be separated by settling or simple filtration.
Solubility: A substance that dissolves in a solvent is described as soluble.
Saturation: A solution is saturated when it contains the maximum amount of solute that can dissolve at a given temperature.

Example: Salt (solute) dissolved in water (solvent) to form saline solution.

A suspension is a heterogeneous mixture where solid particles are dispersed in a liquid but do not dissolve.

Separation: The solid particles can be separated by settling (decantation) or filtration.
Appearance: The mixture is typically cloudy and particles may be visible.

Example: Sand mixed with water.
