Separation Techniques Settling Filtration Evaporation Crystallization Distillation Separating funnel Magnetism Paper chromatography Decanting **You will write these definitions on your practice problems, not in your notebook as key concepts
Settling Used to separate substances with different weights
Filtration Used to separate immiscible solids from liquids
Evaporation Separate dissolved solids from liquids
Slow formation of a solid from a warm solution that is cooled Crystallization
Distillation Used to separate 2 miscible liquids Miscible = MixM&M It is made possible due to the fact that each liquid has its unique boiling point.
Separating Funnel Used to separate two immiscible liquids with different densities
Magnetism Used to separate solids from one another based upon differences in their magnetic properties
Paper Chromatography Used to separate soluble substances from one another based upon differences in retention rates as a solvent moves over paper.
Decanting Used to separate an insoluble solid from a liquid by carefully pouring off the liquid. Based upon differences in density
When will I ever use this?? Scientists use different separation techniques every day –Isolating drugs from blood and urine –Panning for gold –Mining purification
