Explain how a mixture of two liquids with close boiling points is separated.
Original Khojo Papers practice question — not from a past board paper.
Answer
Fractional distillation is used. The mixture is boiled and the vapour passed up a fractionating column packed so that it offers many surfaces for repeated condensation and re-evaporation. Each cycle enriches the vapour in the more volatile component, so the two are separated even when their boiling points are close.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Simple distillation suffices only when the boiling points differ widely.
