Question

Decantation is a:

• A. process of transferring the clear liquid without disturbing the sediments.
• B. process of separating an insoluble solid from a liquid using filter paper.
• C. process of settling down heavier, insoluble particles from a mixture.
• D. process in which a solid changes directly into the vapour state.

Answer 1

Answer: (A)

process of transferring the clear liquid without disturbing the sediments.

Decantation is a process in which the clear liquid is transferred to another container without disturbing the sediments. Decantation is always followed by sedimentation.

In this process first, the mixture of liquid and insoluble substance undergoes sedimentation where the heavier particles get settled down to the bottom of the container then the clear liquid which is forming the upper layer is transferred to another container.
