Answer:

There are many ways/methods to separate water and oil, and even one of the method is given by "Shazia1060", but if you want another method it's written below (hope it helps you)

Explanation:

Using a separating funnel:

A separating funnel is used for the separation of components of a mixture between two immiscible liquid phases. One phase is the aqueous phase and the other phase is an organic solvent. This separation is based on the differences in the densities of the liquids. The liquid having more density forms the lower layer and the liquid having less density forms the upper layer.

Applications:
