You are given a mixture of sand, water and mustard oil. How will you separate the components of the mixture.
Take the mixture of sand, water and mustard oil. Let the solution to stand undisturbed for about half an hour. The heavy sand particles settle down at the bottom of the container. Now transfer the liquid to another beaker in such a way that the sand remains in the first beaker.
Take the remaining mixture of mustard oil and water in a separating funnel. Let the funnel to stand undisturbed for half an hour. Water and mustard oil forms two distinct layers. Oil being lighter forms upper layer while the water forms lower layer. Open the tap of the separating funnel and let the lower layer to collect down in the beaker. Close the tap when lower water layer is completely separated. Take out the oil layer in another beaker. Thus the components of mixture are separated.
