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