Separating Mixtures

Methods:

1. ==Decanting==
2. $Filtration$
3. %%Evaporation%%
4. ^^Chromatography^^

]]Decanting]]

• The insoluble solid sinks to the bottom or is left in the container eg: sand
• The liquid is poured off eg: water

]]@@Filtration@@]]

• Filtration separates small insoluble solids from a liquid eg: sand and water
• Filter paper has tiny holes that let the liquid through but not the solid

}}%%Evaporation%%}}

• Liquid evaporates
• Example: Water and salt => water evaporates and salt stays behind

<<Chromatography<<

• Paper chromatography is a method of separating mixtures of a substance in solution
• The solvent in which the substances are dissolved is passed along a length of paper and the dissolved substances separate out on paper
