Question

By which process can we separate camphor from ammonium chloride?

• A. Filtration
• B. Sublimation
• C. Dissolution and evaporation
• D. Distillation

Answer 1

The correct option is C Dissolution and evaporation

The mixture of camphor and ammonium chloride cannot be separated by sublimation method since both are volatile substances. Thus the mixture is dissolved in water. Ammonium chloride is soluble in water while camphor is not thus the water containing ammonium chloride is decanted in another beaker. Thus camphor is obtained and now the solution is evaporated to separate ammonium chloride. The solution containing ammonium chloride is heated and boiled off the ammonium chloride is left behind
