<<. Evaporation is used to separate a soluble solid from a liquid. For example, copper sulfate is soluble in water – its crystals dissolve in water to form copper sulfate solution. During evaporation, the water evaporates away leaving solid copper sulfate crystals behind.
2. DISTILLATION
<<.Simple distillation is a method for separating the solvent from a solution. For example, water can be separated from salt solution by simple distillation. This method works because water has a much lower boiling point than salt. When the solution is heated, the water evaporates. It is then cooled and condensed into a separate container. The salt does not evaporate and so it stays behind.
3. CHROMATOGRAPHY
<<. In chemical analysis, chromatography is a laboratory technique for the separation of a mixture into its components. The mixture is dissolved in a fluid solvent called the mobile phase, which carries it through a system on which a material called the stationary phase is fixed.
EXAMPLES
Creating vaccinations. Chromatography is useful in determining which antibodies fight various diseases and viruses. ...
Food testing. ...
Beverage testing. ...
Drug testing. ...
Forensic testing.
4. FILTRATION
<<.Filtration is a method for separating an insoluble solid from a liquid. When a mixture of sand and water is filtered:
EXAMPLES
the sand stays behind in the filter paper (it becomes the residue)
the water passes through the filter
5. DECANTATION
<<.Decantation is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension.[1] The layer closer to the top of the container—the less dense of the two liquids, or the liquid from which the precipitate or sediment has settled out—is poured off, leaving the other component or the denser liquid of the mixture behind.
EXAMPLES
Oil and water: Oil floats on top of water. ...
Dirt and water: Decantation is one way to clean muddy water. ...
Kerosene and water (or gasoline and water): The kerosene or gasoline floats above the water. ...
Milk and cream: Decantation separates cream from milk
