Write down the principle and 3 applications of centrifugation, simple distillation
and chromatography
Answers
Answer:
Centrifugation- Separating the suspended particles of a substance from a liquid in which the mixture is rotated at a high speed in a centrifuge.
The process of centrifugation is used in dairies to separate cream from milk.
In simple distillation, a mixture is heated to change the most volatile component from a liquid into vapor. The vapor rises and passes into a condenser. Usually, the condenser is cooled (e.g., by running cold water around it) to promote condensation of the vapor, which is collected.
Most commonly, simple distillation is used in the production of alcoholic beverages such as vodka and whiskey. The simple distillation process relies on the difference in boiling point between ethanol (alcohol) and the mixture or 'mash' used for fermentation and the initial synthesis of alcohol.
Chromatography-Separating two (or more) dissolved solids which are present in a solution in very small quantities.
By paper chromatography two or more different substances present in the same solution can be separated. Two or more substances may be soluble in the same solvent but their solubilities are different.
Black ink in a mixture of several coloured substances can be separated by this method.
