प्रश्न
How will you separate sand and water from their mixture?
Advertisements
उत्तर
Sand is not soluble in water. Hence, the mixture of sand and water can be separated by two methods:
- Combination of sedimentation and decantation: As sand is insoluble and heavier than water, it settles down at the bottom of the container containing the mixture. This process is called sedimentation. After the process of sedimentation is complete, water is slowly transferred to another container and sand remains in the original container. This process is called decantation.
- Filtration: the mixture is poured on a strainer or a piece of cloth or filter paper so that the water goes through the strainer and the sand remains on the strainer.
