Seperation Techniques Flashcards
A no dissolving solid mixed with a liquid
Filtration
Two colorless liquids
Distillation
Red and blue marbles of the same size and mass
Manual separation
Iron fillings in sand
A magnet can be used to draw the iron fillings from the sand
Sand and salt
Add water to dissolve the mixture. Filter the mixture to remove the sand. Boil off the water so only the salt remains.
Components of ink
Paper chromatography
Helium and oxygen gases
Cool the gas mixture until it condenses, then distill the condensate
Technique used to separate mixtures compounds of solids and liquids. Uses a barrier to separate a solid and liquid.
Filtration
Used for most homogeneous mixtures. The mixture is heated until the substance with the lowest boiling point boils to a vapor that can then be condensed into a liquid and collected
Distillation
A separation technique that produces pure solid particles of a substance from a solution that contains the dissolved substances.
Crystallization
The process during which a solid changes to vapor without melting, i.e. without going through the liquid phase.
Sublimation
A technique that separates the components of a mixture dissolved in either gas or a liquid based on the ability of each component to travel or to be drawn across the surface of a fixed substrate.
