FILTRATIONworks by removing particles large enough to get caught by a barrier

Sep 3­8:49 PM

EVAPORATIONif you're not interested in the liquid, allow it to evaporate and leave the solid behind

DECANTINGlet the solid settle then pour the liquid off the top

Sep 3­8:49 PM

DISTILLATIONdistilling the liquid in another container using heat to keep liquid

also used when you have 2 liquids with different boiling points, like crude oil!

CENTRIFUGATIONused to separate a solid with a different DENSITY than the liquid, like with BLOOD

Sep 3­8:49 PM

CHROMATOGRAPHYused to separate components in a dye* a solvent moves up a paper by capillary action* as the solvent meets the mixture, it dissolves it and moves up the paper* diff. compounds in the mixture move at diff. rates due to diff. solubilities
