Demonstration of Separating Techniques

ALL MIXED UP!

CRYSTALLISATION

• 
• Pie de imagen: Crystallisation Apparatus
• The solvent (liquid) is separated from the solute (solid).
• This technique works by evaporating the water leaving behind the solute.

CHROMOTOGRAPHY

• 
• Pie de imagen: Chromatography Apparatus
• Separates liquids from liquids
• The technique works by separating parts of mixtures according to their different solubilities in a particular solvent.

CENTRIFUGING

• 
• Pie de imagen: Centrifuge
• Used to seperate solid or liquid substances from liquids
• Usually a suspension
• The technique works by the heavier substances sink to the bottom when spun around creating a sediment which can then be decanted.

SEPARATING FUNNEL

• 
• Pie de imagen: Separating Funnel
• Used to separate less dense liquid from more dense liquid
• Used to separate liquids with different densities--that do not mix

DECANTING

• 
• Pie de imagen: Decanting Apparatus
• Used to separated liquid from solid or denser liquid
• The technique works by pouring liquid off the top when the sediment has settled to the bottom.

MAGNETIC SEPARATION

• 
• Pie de imagen: Magnetic Separation Apparatus
• Used to separate magnetic and no-magnetic substances
• This technique works by separating a magnetic substance from a non-magnetic substance in a mixture.

FLOATATION

• 
• Pie de imagen: Floatation
• Separation of a solid from a liquid
• Separating out insoluble substances (solids) from a solution if it floats).

DISTILLATION

• 
• Pie de imagen: Distillation Apparatus
• The components in the mixture to be separated is the liquid from the solution.
• The technique works from evaporating to condensation.
• The technique works by: the process that uses evaporation to separate substances that boils at different temperatures.
