What is decantation? Explain.
Decantation is the process of separation of insoluble solids from liquids. A suspension of solid particles in a liquid is allowed to stand for sometimes. Insoluble solid particles settle down at the bottom due to their weight. This is called sedimentation. The clear liquid is then transferred into another container, without disturbing the settled particles. In other words clear liquid is decanted and separated from solid.
