Which type of mixtures can be separated by sedimentation and decantation ? Provide 5 examples of such mixtures?
Answers
Answer:
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.Evaporation can be used to separate a solid dissolved in a liquid.
A saturated solution is one in which no more of that substance can be dissolved.
More of a substance can be dissolved in a solution by heating it.
Water dissolves different amount of soluble substances in it.
The process to settle down the heavier particles present in a liquid mixture is known as sedimentation.
The process of separating the liquid after the particles have settled, called the sediments, is known as decantation.
The process of sedimentation followed by decantation can be used in the following cases :
- to settle down the heavier particles present in a liquid mixture.
- Oil and water
- Milk and cream:
- To purify impure water.
- from muddy water to a sample of clear water
