Which of the following mixtures is most suitably separated by the technique of sublimation?

Step-by-step solution

Sublimation is a technique used to separate a sublimable volatile component from a non-sublimable impurity. Camphor is a sublimable solid, whereas sodium chloride is a non-sublimable solid. Thus, a mixture of camphor and sodium chloride can be easily separated by sublimation. Glycerol and spent-lye are separated by distillation under reduced pressure. Aniline and water are separated by steam distillation. Benzene and toluene are separated by fractional distillation. Answer: Camphor and sodium chloride
