The oldest methods used for separation and purification include settling down of impurities and filtering them out to obtain the pure product components. Separation of substances from a mixture requires specific techniques for different sizes and types of substances. This module talks about two important separation techniques like sedimentation and filtration. Sedimentation uses the principle where the particles are not soluble in the solvent and hence settle in the bottom of the mixture separating the two components. Filtration uses the principle of selective separation where the particle...
