Practice question
Question
Which purification technique is most effective for separating a mixture of two liquids, one boiling at 100°C and soluble in water, the other boiling at 120°C and insoluble in water?
Explanation
Differential extraction uses water to dissolve the soluble liquid (b.p. 100°C), separating it from the insoluble one (b.p. 120°C), leveraging solubility over boiling point difference.
