Sedimentation, Decantation, and Filtration – Definition

Answer:

• Sedimentation – The process of heavier particles of an insoluble solid settling down in a liquid is known as sedimentation. It is a technique for separating mixtures of chemicals.
• Decantation is the process of removing liquid from a container without disturbing the sediment.
• A method for separating an insoluble substance from a liquid is filtration. When a sand and water mixture is filtered using filter paper. The sand remains in the filter paper (it becomes the residue), while the water passes through (it becomes the filtrate).
