Question

How insoluble impurities are separated from water?

Answer 1

Answer:

Explanation:

In a mixture of sand and water, the heavier sand particles settle down at the bottom and the water can be separated by decantation. Filtration can be used to separate components of a mixture of an insoluble solid and a liquid. Evaporation is the process in which a liquid gets converted into its vapour.

Answer 2

Answer: To remove insoluble substances from water, Sedimentation and Decantation processes are used.

Explanation: 1. Sedimentation: Suppose you have a mixture of sand and water. Then you need to keep that mixture in a container in order to settle down the particles of San in water at the bottom of the container. The process of settling down of sand particles is known as sedimentation.

2. Decantation: Then after settling down of the sand particles, kindly pour down the water in another container.
