State the principle of separating two immiscible liquids by separating funnel. Describe an activity with diagram to separate a mixture of water and kerosene oil.
Immiscible layers separate out in layers depending on their densities in separating funnel.
Activity to separate kerosene oil from water using a separating funnel:
- Pour the mixture of kerosene oil and water in separating funnel as shown in figure.
- Let it stand undisturbed for sometime so that separate layers of oil and water are formed.
- Open the stopcock of the separating funnel and pour out the lower layer of water carefully.
- Close the stopcock of the separating funnel as the oil reaches the stopcock.
