On what principle are the following methods of separation based? Give one example of a mixture for each of the methods mentioned in which they are used.​
By using a separating funnel​

The principle of separating funnels is that immiscible liquids separate out in layers depending on their densities.​ ​

• It is a simple device used to separate the components of a liquid-liquid heterogeneous mixture.​ ​

Example : ​ Mixture of kerosene oil and water. Water being denser gets separated out first.​
