What process could be used to purify potassium chloride?
Crystallization/recrystallization process can be used.
What is the purpose of the sublimation and recrystallization steps?
Recrystallization and Sublimation are two commonly encountered methods of Purification. Several of these are done in the laboratory to obtain a pure sample of a particular organic compound. Recrystallization literally means to crystallize again. Sublimation involves heating the compound at low pressure from one apparatus and and condensing it in another. This is quite the same as distillation but of solid state.
