Explain the separating funnel method?
What is the two liquids in the mixture have different densities, making the heavier liquid settle at the base of the container. In this setup, a funnel with a tap at the spout is placed inside a beaker.
The mixture is poured into the funnel and allowed to settle. Soon, the oil, which is heavier, settles at the base, with the water on top of it. The tap is opened to allow the oil to pass, and closed as soon as the water reached the spout.
