Distillation, Filtration, evaporation, and Chromatography
The filtration process is generally used to separate a suspension mixture where small solid particles are suspended in liquid or air.
Distillation uses boiling to separate mixtures of liquid solutions. It takes into account that different substances in the mixture will have different boiling points..
Chromatography is the separation of a mixture by passing it in solution or suspension or as a vapor (as in gas chromatography) through a medium in which the components move at different rates
Evaporation is a technique used to separate out homogenous mixtures where there is one or more dissolved solids. This method drives off the liquid components from the solid components
