Question

Explain the technique of separation of immiscible liquids by using a separating funnel?

Answer 1

Separating funnel:

• A separating funnel is an apparatus that is used to separate immiscible liquids.
• During the separation, the heavier liquid forms the lower layer, and the lighter liquids form the upper layer.

The technique of separation:

• The immiscible liquid, oil and water are taken in a separating funnel.
• The immiscible liquid forms two clear layers.
• The lighter liquid that is oil forms the upper layer and the heavier liquid that is water forms the lower layer.
• When the stopper of the funnel is opened gradually the water comes out first and is collected in a beaker.
• When the lower layer is shipped completely, the stopper of the funnel is closed.
• The lighter liquid is left in the separating funnel.
