What is centrifugation. Explain with example |
|
Answer» It is a method of separating the suspended particles of a substance from a liquid in which the mixture is rotated at high speed in a centrifuge.This method is useful in case the suspended particles in a liquid are too small too be retained by filter paper.Principle of Centrifugation:When a mixture is rotated very fast, the denser particles are forced to go to the bottom of the centrifuge and the lighter particles stay at the top.Applications of Centrifugation:Used in dairies to separate cream from milk.Used in washing machines to squeeze out water from wet clothes. \xa0Centrifugation.Answer:\xa0Sometimes the solid particles in a liquid are very small and pass through a filter paper. For such particles the filtration technique cannot be used for separation. Such mixtures are separated by centrifugation. The principle is that the denser particles are forced to the bottom and the lighter particles stay at the top when spun rapidly. |
