Question

Name the process by which sand is separated from its mixture in water.

Answer 1

• Sedimentation is the process by which heavier impurities in a liquid settle on the bottom of the container containing the mixture.
• The process of pouring the clear supernatant liquid without disturbing the sediment is called decantation.
• The sand particles are heavy when the sand solution is left undisturbed for some time, so the sand particles settle down at the bottom.
• Now, pour the upper layer of water into another beaker by the process of decantation.

Hence, sand is separated from its mixture in water by the process of sedimentation and decantation.
