    By which process can we separate camphor from ammonium chloride?

    A)  Filtration

    B)  Sublimation

    C)  Dissolution and evaporation  

    D)  Distillation

    Correct Answer: C

    Solution :

     Camphor and ammonium chloride both sublime on heating, hence they can be separated by pouring the mixture into water (solvent extraction). Ammonium chloride dissolves in water leaving behind camphor. Ammonium chloride is recovered later by evaporating the water slowly.
