What is a separating funnel method? How can a separating funnel be used to separate kerosene and water? Explain with a drawing figure.
A separating funnel is a funnel that is used to separate immiscible liquids.
Liquids that do not mix with each other are said to be immiscible.
Two immiscible liquids, such as oil and water, can be separated by using a separating funnel.
Method of separation of kerosene and water:
Procedure:
Pour a mixture of kerosene and water into a separating funnel with its stopcock closed. Close the stopper. Fix the separating funnel firmly on a stand. Leave the mixture in the funnel undisturbed for a while. Water will remain below and kerosene will float on it.
Now, without shaking the funnel, remove the stopper. Open the stopcock to collect the water at the bottom of the funnel, in a beaker. Close the stopcock when all the water is collected in the beaker. Now, kerosene and water are separated.
