Question

write the basic principle behind a chromatography b crystallisation c distillation d centrifugation

Answer 1

Chromatography is a process of separating two or more solids mix I a liquid .In chromatography solids are separated according to their solubility in water.

Crystallisation is a process of getting pure element by cooling a concentrated solution.

Distillation is a process in which two miscible liquid are separated when difference between their boiling point is more than 25°c

centrifugation is a process of separating solid mix in liquid by taking the solution in a tube and moving the tube at a high speed.Due to heaviness of soli, solid settle down in the tube....

Answer 2

a )chromatography= both solute should be dipped in same solvent and chromatography in ancient time is used to separate colours from the nature
b )crystallization= it is used to separate the pure substance in the form of crystals like Salt from water
c) distillation= it is used to separate two miscible liquids whose boiling point is more than 25 degree Celsius
d) centrifugation= it is used to separate alight solution like l butter from cream
