Mixtures Categorize a sample of matter as a substance or a mixture.Distinguish between homogeneous and heterogeneous samples of matter.Describe two ways that components of mixtures can be separated.
Classifying Mixtures • A mixture is a physical blend of two or more components. • A mixture in which the composition is not uniform throughout is a heterogeneous mixture. • A homogeneous mixture is a mixture in which the composition is uniform throughout. (aka a solution)
Separating Mixtures • Differences in physical properties can be used to separate mixtures. • The process that separates a solid from a liquid in a heterogeneous mixture is called filtration. • During a distillation, a liquid is boiled to produce a vapor that is then condensed into a liquid.
