Separating Mixtures What is a mixture? When two or more materials or substances are mixed together but do not chemically combine.
This means they retain their original properties. This means they can be separated by physical means. What are the different ways of separating mixtures?
Magnetism Hand separation
Filtration Sifting or sieving Extraction and evaporation Chromatography Magnetism If one component of the mixture has magnetic properties, you could use a magnet to
separate the mixture. Iron, nickel, and cobalt are all materials that are magnetic. Not all metals are magnetic: gold, silver, and aluminum are examples of metals that are not magnetic. Example of magnetism Using a magnet to separate nails from wood
chips. Hand separation Separating the parts of a mixture by hand. Only useful when the particles are large enough to be seen clearly. Useful for: separating parts of a salad.
Example of hand separation: Using your fork to separate tomatoes, lettuce, cucumber, onions, etc. in your salad. Filtration Used when separating a solid substance from a fluid (a liquid or a gas) by passing a mixture through a porous material such as a type of
filter. Works by letting the fluid pass through but not the solid. Examples of filters: coffee filter, cloth, oil filter, even sand! Example of filtration: Using a coffee filter to separate the coffee
flavor from the coffee beans. Sifting or sieving Used to separate a dry mixture which contains substances of different sizes by passing it through a sieve, a device containing
tiny holes. Extraction Used to separate an insoluble solid (something that doesnt dissolve in a liquid) from a soluble solid (something that DOES dissolve in a liquid). Done by adding a solvent (liquid that does the dissolving) to the
mixture. Then pouring the liquid through a filter. Example of extraction With a mixture of sugar and sand, pouring water in the mixture which causes the sugar to dissolve. Then pouring the solution through a filter, causing the sand to separate
from the sugar water. Evaporation Allowing the liquid to evaporate, leaving the soluble solid behind. Example: heating
sugar water. The water evaporates and the sugar crystals are left behind. Example of using extraction and evaporation together:
Using water to dissolve sugar, then letting the water evaporate, leaving the sugar behind. Chromatography Used to separate dissolved substances in a solution from each other. Stationary Phase
Separation Mobile Phase Mixture Components
Example of chromatography: Using chromatography paper to separate ink into its original components.
