use of Sieving

separate different substances of different particle sizes

use of Centrifuging

used to settle an insoluble solid from a liquid or to remove a liquid from a substance

use of separatory funnel

 used to remove a liquid from another liquid which is not miscible and has a different density.

use of Filtration

used to remove an insoluble solid from a liquid.

use of Evaporation

used to separate a soluble solid from a liquid.

use of Distillation

used to separate two liquids from each other which have different boiling points. It can also be used to separate a liquid from a soluble solid.

use of Magnetism

used to remove the metals containing Nickel, Iron or Cobalt from a solid.

use of Chromatography

used to separate mixtures of dissolved substances

filtrate

the liquid that has been filtered, that is, the liquid that has passed through the paper

filtration

a method of separating an insoluble solid from a liquid using a material that allows the liquid to pass through but not the solid

distillation

the vaporising of a liquid by boiling it and then condensing the vapour by cooling it

distillate

the purified liquid produced by condensation from a vapour during distillation

chromatogram

the strip of paper on which the parts of a mixture have been separated by chromatography

paper chromatography

a method of separating mixtures of substances in solution. the solvent in which the substances are dissolved is passed along a length of paper and the dissolved substances separate out on the paper
