Four method of mixture

A

Filtration

Chromatography

17
Q

Filtration

A

Used to separate small insoluble solids (do not dissolve in a liquid) from a liquid using filter paper and funnel to trap the solids.

18
Q

Evaporation

A

Used to separate soluble solids (dissolve in liquids) from a solution by evaporating off the liquid to leave the solids. E.g. salt water.
