--chemanical mixture or heterogeneous mixture can be separate by using a magnet or sieve
--evaporation (solid dissolved in liquid solution)
--boil away the liquid and the solid remains
Filtration (Solid which is not dissolved in water)
--if pores are smaller than particles, solid particles stay on filter and liquid/gaseous components pass through often used after separation by precipitation
--use filter paper (residue left in filter paper)
Crystallization (Solid in Liquid)
--a solute to solid form by cfhemical or physical change
--solids are separate by filtretion or floatation
--evaporate or cool: solid comes out as pure crystals
Gravity Separation (Solids based on density)
--a centrifuge whirls the test tube around at high speeds forring the denser materials to the bottom.
--best for small volumes
Solvent extraction (Solid and Solid)
--use liquid to dissolve one solid bur not the other so the desired solid is left behind or be solved
--solvent is insoluble with solvet already present
Distillation (Liquid and Liquid)
--liquid with lower boiling pront first-vapour ascents to distillation flesk and enters condenser and then gas cools and condenses back to liquid drop the distillate as a parified liquid
Chromatography
--mpbile phase sweeps the sample over a stationary phase
--can separate very complex mixtures
--separated components be collected individually
Sheet Chromatography
--Paper chromatography
--TLC (Thin Layer Chromatography)
