You are given a mixture of water, groundnut oil, and common salt. How will you separate groundnut oil and common salt from it?
To separate the water, groundnut oil, and common salt from the given mixture following steps should be followed:
- Pour the mixture in a separating funnel and leave it for some time. As both salt solution and oil are immiscible, water settles down and oil will keep floating because of the difference in their densities.
- Open the stop–cock and take out the salt solution in the beaker. Groundnut oil is left in the funnel.
- On evaporating the contents of the beaker, water will evaporate and salt will be left behind as residue.
