Chemistry - Decanting to separate liquids

Decanting to separate liquids

Immiscible [1] liquids can be separated by decanting. [2]

In this technique the liquids are allowed to settle so that the least
dense liquid forms a layer above the denser liquid. The less dense liquid
can then be poured into a separate container.

A separation funnel allows the liquids to be separated much more
accurately. The liquids are poured into the separation funnel and allowed
to settle. Then a tap in the bottom of the separation funnel is opened and
the denser liquid is removed into a separate container.
