19-20 Separation Techniques
Decanting
A method of separating solid insoluble particles from a liquid by leaving the particles to settle and pouring off the liquid.
Sublimation
A method where the substances change from a solid that sublimes upon heating from another substance with a high melting point.
Chromatography
A technique that is used to separate the components of a mixture based on molecular attractions and the tendency of each component to travel or be drawn across the surface of another material.
Distillation
A technique that separates the substances in a solution based on their boiling points. Vapor is condensed and collected as a pure liquid.
Magnetic separation
Separating out the magnetic parts of a mixture using a magnet
Crystallization
a separation technique that produces pure solid particles of a substance from a solution that contains the dissolved substance
Filtration
a technique that uses a porous barrier to separate a solid from a liquid
Evaporation
is used for the separation of soluble solids and solvents. In this separation method, a solution is heated until the solvent evaporates, leaving behind a solid residue.
