Separation of mixtures

From the edexcel international gcse chemistry revison guide.

?
Filtration
To seperate an undissolved solid from a mixture of the solid and liquid/solution (e.g. sand from a mixture of sand and water)
1 of 6
Evaporation
To separate a dissolved solid from a solution, when the solid has similar solubilities in both cold and hot solvent (e.g. sodium chloride from a solution of sodium chloride in water)
2 of 6
Crystallisation
To separate a dissolved solid from a solution, when the solid is much more soluble in hot solvent than in cold (e.g. copper(II) sulfate in water)
3 of 6
Simple distillation
To separate a liquid from a solution (e.g. water from a solution of sodium chloride in water)
4 of 6
Fractional distillation
To separate two or more liquids that are miscible with one another (e.g. ethanol and water from a mixture of the two)
5 of 6
Paper chromatography
To separate substances that have different solubilities in a given solvent (e.g. different coloured inks that have been mixed to make black ink)
