Class 9 chapter 2 various separation process types of separation process |
|
Answer» Answer: there are various types of separation methods for example filtration, chromatography, sublimation, distillation, fractional distillation, crystallization, purification etc. filtration: it is the process in which the substance can be e separated very simply using a funnel, test tube, filtrate and a filter paper. chromatography: a technique for the separation of a mixture by passing it in SOLUTION or suspension through a medium in which the components move at different rates. sublimation: sublimation is the process in which SOLIDS directly convert into gas without passing through liquid which can be used to separate ammonium chloride and salt. distillation: the action of purifying a liquid by a process of heating and cooling. fractional distillation:separation of a liquid mixture into fractions differing in boiling point (and hence chemical composition) by means of distillation, typically using a fractionating column. crystallization:Crystallization or crystallisation is the (natural or artificial) process by which a solid forms, where the atoms or molecules are highly ORGANIZED into a STRUCTURE known as a crystal. Some of the ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas. purification: the process of extracting something from a substance. |
