Technique 6: Separation of immiscible liquids using a Separating Funnel

Separation of 2 or more immiscible liquids can be done using a separating funnel. When 2 liquids do not dissolve into one another, they are separated by the difference in their densities. For example, Oil being less dense than water, floats on its surface, in their mixture.

Figure 9b shows the mixture of oil over water in a separating funnel. The tap is opened to collect water in a beaker and oil in another. Like other separating techniques, this too does not yield 100% purity and both liquids may contain traces of the other.
