Question:

While diluting a solution of salt in water, a student by mistake added acetone (boiling point $56^{\circ} \mathrm{C}$ ). What technique can be employed to get back acetone? Justify your choice.

Solution:

Acetone can be recovered by carrying out the distillation in a distillation flask. Its vapours will rise since it is volatile, get condensed and collected in a receiver. Salt being non-volatile in nature remains in the flask.
