Separation Techniques

Simple Distillation Used to separate a liquid and a solid that are in solution Liquid is collected E.g: Obtaining pure water from salty water

Fractional Distillation Used to separate liquids with different boiling points E.g: Obtaining different fractions from crude oil

Filtration Used to separate a liquid and a solid that is insoluble Liquid filtrate passes through the filter paper Solid residue remains on the filter paper E.g: Sand and water

Crystallisation Used to separate a liquid and a solid that are in solution Only solid is collected E.g: Obtaining salt from salty water

Paper Chromatography Used to separate solids that are dissolved in the same solvent Solid that is most soluble travels the furthest Each dot represents a different solid E.g: Different inks
