seperating mixtures

• What is filtration?

  separating insoluble solids from a liquid
• What is crystallisation?

  separates soluble solids from a liquid
• What is simple distillation?

  separating liquid solvents from dissolved solids
• What is fractional distillation?

  separating two or more liquids with different boiling points
• What is chromatography?

  separating two or more dissolved solids from a solution
• What is the substance left behind after filtering called?

  residue
• What is the liquid from filtration called?

  filtrate
• What happens to the vapours when they go through a condenser?

  they cool down and condense
• What is in a condenser that causes vapours to condense?

  Cool water flows around to cool the vapours
• Give an example of when simple distillation is used.

  Purifying salty water
• How can you check water has been purified?

  check it boils at its expected boiling point
• In fractional distillation, the liquid with the lower boiling point evaporates..

  first
• The fractioning column in fractional distillation slows down vapours.
