Separating funnel
A mixture of immiscible liquids(emulsions) can be separated using a separating funnel. The separation of emulsions is based on the principle that the lighter liquid will float above the heavier liquid.
A separating funnel is a glass bulb with a tap called a stopcock attached to its bottom. The stopcock is used to control the flow of the liquid.
To separate the components of an emulsion, the mixture is put into a separating funnel and allowed to settle.
After some time, the liquids form separate layers, one above the other.
The liquid forming the lower layer is collected in a container by opening the stopcock. The stopcock is closed after the liquid in the lower layer is collected completely.
The liquid forming the upper layer is collected similarly in another container.
Example: Kerosene oil can be separated from water using a separating funnel.
