Question

what is the principal for decantation? ​

Answer 1

Settling down of particles under gravity.

Answer 2

• The principle of sedimentation is that heavy particles settle faster in a medium. So the solid component which is insoluble in the mixture settles down due to gravity. Decantation is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension.
