Mixtures

Mixtures are two or more substances which are not combined chemically. Therefore each substance in a mixture retains the same properties as if it were alone.

Separating Mixtures

All mixtures may be separated by physical properties.

distillation separates solutions based on the boiling point of the components
Distillation – Separates solutions based on the boiling point of the components.

Condensate

Distillate

Fractional Distillation – is a widely used distillation method in the petroleum industry. Different fuels have different volatility (boiling points) which allow them to be separated from crude petroleum.

Gasoline

Kerosene

Heating Oil

Aviation Fuel

Asphalt

Chromatography – The separation of a solution on the basis of solubility. The furthest point from the bottom of the paper is called the solvent front.

Chromatography – The origin is the point on the chromatography paper where the solute (what is being dissolved) and the solvent (what is doing the dissolving) initially meet).
