2. Classiifying Mixtures Heterogeneous Components not uniform Examples: soup, salad, … Homogeneous Components are uniform Examples: tea, soda,… Phase: a part of a mixture that is uniform

3. Classifying Mixtures Heterogeneous Mixtures Homogeneous Mixtures Composition is not uniform Parts can be distinguished from each other Consists of two or more phases Composition is uniform Parts cannot be distinguished from each other A.K.A. Solutions Consists of a single phase

4. Separating Mixtures Based on physical properties such as Solubility ….. filtration Boiling point….. distillation Melting point Color….sorting

5. Separating Mixtures Use Differences in Physical Properties Solubility Density Boiling Point Particle Size Magnetic Attraction

6. Review How are mixtures classified? What type of properties can be used to separate mixtures? Explain the term “phase” How are a substance and a solution similar? How are a substance and a solution different?
