Question

24. Explain an activity to separate a mixture of sand and water using sedimentation and decantation.​

Answer 1

Sand and water can be separated by any of the following two methods:

(a) Sedimentation and decantation: Mixture is kept undisturbed for some time. After some time, sand being heavier and insoluble in water, settles down at the bottom of container. Now, water is poured into another container to separate it from sand.

(b) Filtration: Mixture of sand and water is passed through a filter paper (a filter with very fine pores). Sand particles being larger in size are retained by the filter paper and get separated from water.

Explanation:

We will separate sand and water by sedimentation and decantation method. First we leave this mixture for some time. After some time, the sand which is heavier is settled down at the bottom. After that we will pour water into another container and the mixture will be separated.
