R ECALL : A mixture is the (physical / chemical) combination of 2 or more ____________. Compounds are the ( chemical / physical) combination of 2 or more __________. Mixtures can be broken into two more classifications: ________________ & ________________ Compounds can only be separated (physically / chemically) Mixtures can only be separated (physically / chemically)

J. S EPARATING M IXTURES Filtration Separates a solid from the liquid in a heterogeneous mixture using a porous barrier. Example: A colander is used to separate pasta from the water in which it was cooked.

J. S EPARATING M IXTURES C ONT. Distillation Separates mixtures based on difference in boiling points of components in the mixture. A liquid is boiled to produce a vapor that is then condensed into a liquid. Example: Distilled Water

J. S EPARATING M IXTURES C ONT. Crystallization Separates mixtures by forming pure solid particles in a solution containing the dissolved solute. Example: Rock candy.

J. S EPARATING M IXTURES C ONT. Chromatography Separates the components of a mixture because components travel across a surface at different rates.
