Filtration
A method used to separate insoluble solids from liquids by allowing the liquid to drain through tiny openings in a material.

Study Notes
Separation Techniques
-
Filter: A device with small openings used to separate solids from liquids or gases. Insoluble solids remain, while the liquid or gas passes through as filtrate.
-
Decantation: A method to remove solids like rust, dirt, and sand from a liquid. The liquid is poured off leaving the solid behind.
-
Chromatography: A technique that separates components of a mixture. The mixture is passed through a material that absorbs components differently.
-
Capillary Action: The adhesion of water to a filter paper causing water to move up the paper. This helps separate substances based on their differing solubilities.
-
Evaporation: A method to separate a solute from a solution. The solution is heated causing the solvent(liquid) to evaporate, leaving the solute behind. Useful for creating solid substances like salt.
-
Crystallization: A process to separate a saturated solution by heating. The solution is heated until it is saturated, allowing the solute to form crystals.
-
Distillation: Separates components of a mixture based on their different boiling points. The mixture is heated to reach the boiling point of one component, which then evaporates and is collected.
