Question

Which method is best suited for the separation of a mixture of acetone and water?

• A. Vapourisation
• B. Use of separating funnel
• C. Evaporation
• D. Distillation

Answer 1

The correct option is D

Distillation

The mixture of acetone and water is separated using simple distillation. These liquids have a large difference in their boiling points. The boiling point of acetone is ${56}^{0}C$, whereas that of water is ${100}^{0}C$. So, they form vapours at different temperatures and then these vapours can be condensed separately to obtain pure liquids.
