Title: Separation of Mixtures
Description: Honors Chemistry
September 21, 2020




Methods of Separating Mixtures

Physical Methods of Separating
          Lecture: How to Separate Compounds
                    Bird seed (classify…element, compound, mixture)

How would you separate this mixture?
          KIX with gumballs (magnet)
          Electromagnet – flow of electricity creates a magnetic field
               NMR (nuclear magnetic resonance), MRI (magnetic resonance imaging) CAT scan
          Filter (sand)
          Decant
          Evaporation alcohol vs. water
          Distillation
          Evolution: retort (hero’s fountain), round bottom flask with copper tubing, condenser
               Alcohol production from fermentation of grain to yeast urine
               Oil refinery (natural gas, gasoline, kerosene, tar)
               Still
                    MeOH = methyl alcohol (methanol) wood alcohol
                    EtOH = ethyl alcohol (ethanol) grain alcohol
                              Blue-bottle explosion won’t explode a 2nd time (carbon dioxide)
                                     Must replace less dense fluid (CO2) with more dense fluid (water)
          Chromatography – black pen
          Centrifuge
 

Enjoy yourself.
These are the "good old days" you're going to miss in the years ahead.
