Question

Give two examples for which the sedimentation and decantation processes are used.

Answer 1

1. Sedimentation: The process of settling down heavy insoluble particles in a solid-liquid mixture is called sedimentation.
2. Decantation processes: The process of transferring clear liquid after sedimentation, without disturbing the sediment (insoluble heavy particle) is called decantation.
3. This method is adopted to separate heavy insoluble solid substances from a liquid.

Example:

1. Sand and water separation (sand settlement).
2. Oil and vinegar separation,
3. Settled chalk powder, and water separation.
