1. Separating Mixtures Differences in physical properties can be used to separate mixtures What are some physical properties we can use to separate mixtures?

2. Separation Techniques Filtration Separating a solid from a liquid in a heterogeneous mixture

3. Separation Techniques Distillation Distillation - a method of separating substances based on differences in their bp Liquid boils to produce a vapor and is then condensed to a liquid Lower BP separate out first

5. Separating mixtures Distillation - a liquid is boiled to produce a vapor which is condensed into a liquid distillation How to perform simple distillation in the chemistry lab | Wonder How To How to perform simple distillation in the chemistry lab | Wonder How To

6. Separation Techniques Chromatography Physical means Solvent travels up paper by capillary action Solute (pigment) dissolves in solvent to different degrees The more soluble the component is in the solvent, the higher it travels

7. Chromatography Used to identify substances qualitatively and quantitatively Used to separate amino acids, anions Detecting pesticides in food Forensics to analyze the dye composition of fibers

8. Chromatography

9. Rf Values Retention factor Physical property Relationship of distance moved by solute to distance moved by the solvent front Rf = distance moved by solute distance moved by solvent
