Solution
Using a Separating Funnel Principle: This works on the basis that when two liquids are immiscible, they settle in layers. The heavier liquid is below and the lighter above.
Immiscible liquids can be separated using a separating funnel.
The heavier liquid of the two immiscible liquids forms the lower layer and the lighter liquid forms the top layer.
A mixture of mustard oil and water can be separated using a separating funnel.
The mixture is placed in a separating funnel and is allowed to stand for some time.
Two layers of the components are observed.
The lighter liquid (oil) forms the top layer and water being heavier forms the lower layer.
The heavier liquid comes out first on opening the stopper of the funnel and is collected in a container.
The stopper of the funnel is closed once the lower layer is transferred completely.
The lighter liquid remains in the separating funnel.
This method can be used to separate mixtures of oil and water, petrol and water, and carbon tetrachloride and water.
