Question

Method used to separate ammonium chloride and sodium chloride

Answer 1

Explanation:

It can be done by crystallization, filtration or sublimation. 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. The reaction can be written as:

`NH_4Cl _((s)) -> NH_3_(g) + HCl_((g))`

Sodium chloride on the other hand doesn't sublime and has a higher melting point than ammonium chloride
