Seperation Techniques Flashcards
What is Filtration?
Filtration is separating solids from a liquid or a gas by passing it through a filter.
What is Centrifuging?
Centrifuging is spinning a mixture around really fast to separate its two or more parts.
What is Decantation?
Decantation is letting a solid sink to the bottom of a mixture and then slowly pouring it out keeping the sediment in and letting the liquid flow out.
What is Crystallisation?
Crystallisation is a process of letting the really small solids in the suspension of a substance attach together and make a larger version that can be separated.
What is Evaporation?
Evaporation is letting a substance sit somewhere hot and making the liquid heat up and turn into vapor in the air so that all that is left is the solid.
What is Distillation?
Distillation is the process of heating up a substance and then cooling it down. This works as a separation technique because different parts of a substance have different boiling and freezing points.
What is Magnetic Separation?
Magnetic Separation is using a magnet to take out parts that are made of metal and are magnetic.
What is Chromatography?
Chromatography can be used to separate ink colours because of their density.
