Question

Sand and water are separated by the method of:

• A. sieving
• B. sublimation
• C. magnetic separation
• D. decantation

Answer 1

The correct option is D decantation

As sand does not mix water. sand settles down like precipitates. so you can decant it from water. and water can be filtrated to get more clean water.

Decantation is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension.
