Question
Kerosene and water
- Give the principle involved in the separation of the mixture
- Give the technique of separation of the mixture.
Solution
By Separating funnel
Principle – Based on the separation of two in-miscible liquids, one heavy the other light.
Separating funnel – It is a pair-shaped or cylindrical bulb with a stock-cock fitted at its end. The immiscible liquids are allowed to stand in the separating funnel, till the heavier liquid settles below the lighter liquid.
The technique of Separation – The liquid-liquid mixture is added to the separating funnel and the funnel kept aside for some time.
The heavier immiscible liquid settles down in the separating funnel and is then removed from below on opening the tap and collected out separately.
The lighter immiscible liquid remains above the heavier liquid, (immiscible liquids do not mix)
