Question

Explain the following method of separation with an example each.

Sedimentation and decantation.

Answer 1

Sedimentation:

• It is based upon of effect of gravity in the suspension solution.
• In suspension, the practices will settle down at the bottom and get separated.
• The clear liquid solution is seen on top of the beaker.
• Example: The process of sedimentation is used in water treatment plants.

Decantation:

• Decantation is the process of separation of liquid from solid and other immiscible (non-mixing) liquids, by removing the liquid layer at the top from the layer of solid or liquid below.
• It is generally used in the separation of oil and water.
