1. Unit 1 Lecture 6: Separation Techniques
The student can design and/or interpret the results of a separation experiment (filtration, paper chromatography, column chromatography, or distillation) in terms of the relative strength of interactions among and between the components.

2. How can a mixture of two or more substances be separated?
List various methods that can be used to separate a mixture.
Discuss when the method would work the best (i.e. only liquid mixtures, only when a heterogeneous mixture)
Record ideas.
Many examples in the kitchen – strainer, gravy separator, forceps, evaporation

3. How do various separation techniques work?
Visit each station and make observations.
Hypothesize how the process works at the atomic level.
For each station, identify if a physical or chemical property is used in the separation.

4. Station 1: Fractional Distillation

5. Station 2: Centrifuge

6. Station 3: Buchner Funnel Vacuum Filtration

7. Station 4: Magnetism

8. Opps….
You accidently spilled the sugar and pepper together. How would you go about separating the mixture?
