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.
ScienceClass 9CBSEAnswered 27 Mar 2026
Answer
Solution:
Fractional Distillation can be used to separate acetone from the mixture of salt and water.
Explanation
There are considerable differences in the boiling points of acetone (56°C) and water (100°C). When the solution is heated, acetone evaporates first. The water is collected in the distillation flask. The vapours of acetone are then condensed to obtain acetone.
