  1. Methods of Separation Agenda • Explore methods of separation • Notes on methods of separation

  2. Explore • Four methods of separation are set up around the room. • Observe the physical properties before and after. • Determine states of matter separated • Determine properties used to separate

  3. Methods of Separation Date:

  4. Methods of Separation • Distillation – separate liquids by boiling points. • One boils at a lower temperature allowing it to be trapped and condensed. • Occurs with oil and gasoline

  5. Chromatography – separate particles by their ability to travel with a solvent – many types • Ink on paper – lab from crime

  6. Filtration – Separates liquid and solid • pouring mixture into paper, the liquid passes through while paper collects the solid • Coffee, draining spaghetti

  7. Evaporation – heat a liquid to its boiling point so that it evaporates leaving behind the other substances. • You did this one in the lab!

  8. Extraction – dissolving a substance in a solvent in which all other substances are insoluble. • You did this one in the lab!

  9. Sublimation – Separate solids. • Heat mixture so that one of the substances is converted into a gas. Not many substances sublime • Dry ice

  10. Separation Lab • Purpose – separation • don’t want to lose anything! • quantitative • Research: methods of separation
