While diluting a solution of salt in
water, a student by mistake added acetone (boiling point 56°C). What technique can be employed to get
back the acetone? Justify your choice.
Answer: Since, the boiling point of acetone is 56°C and boiling point of water is 100°C, and for distillation the minimum difference in temperature
should be 250°C. Thus by the process of distillation acetone can be separated.
