Question

What is sublimation? Draw a labelled diagram of the experiment set up to demonstrate the sublimation of a ammonium chloride .

Answer 1

We know that ammonium chloride changes directly from solid to gaseous state on heating. So, in order to separate a mixture containing a sublimable volatile component from a non-sublimable impurity (salt in this case), the sublimation process is used.

Sublimation:It is a process in which matter undergoes a phase transition directly from a solid to gaseous form, or vapor, without passing through the more common liquid phase between the two.
