Question

how to separate sodium chloride and ammonium chloride from each other

Answer 1

I think with the help of Sublimation you can separate each other.

Answer 2

Answer:

The easiest method among the three is separation by sublimation. Ammonium chloride sublimes upon heating. Actually, the sublimation is a decomposition of ammonium chloride forming ammonia and hydrogen chloride. Sodium chloride, on the other hand, doesn't sublime and has a higher melting point than ammonium chloride.
