- 1Sieving: It is the method in which two or more components of different sizes are separated from a mixture on the basis of the difference in their sizes.Thus, it cannot separate two substances in a mixture which have the same size. Example: Sand and Gravel.Evaporation:
It is the process whereby atoms or molecules in a liquid state (or solid state if the substance sublimes) gain sufficient energy to enter the gaseous state.
Example: Water and Salt. - 2Distillation: It is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation. Example: Distillation of alcohol.Decantation:
It is allowing a mixture of solid and liquid or two immiscible liquids to settle and separate by gravity.
Example: Oil and water; wine. - 3Crystallization: It is a natural process which occurs as materials solidify from a liquid, or as they precipitate out of a liquid or a gas. Example: Water turns into ice.Filtration:
It is the process of separating suspended solid matter from a liquid, by causing the latter to pass through the pores of some substance called a filter.
Example: When kidneys eliminate toxins from the body. - 4Magnetism: It is the power to attract. It refers to the attraction to iron and other metals in electric currents and magnets. Example: Separating components by isolating metals.Paper Chromatography:
It is a technique for separating dissolved chemical substances by taking advantage of their different rates of migration across sheets of paper.
Example: Identifying fingerprints. - 5Centrifuging: Technique which involves the application of centrifugal force to separate particles from a solution. Example: elimination of impurities.Bibliography:
