Question

57. Explain the suitable method of separation of ammo-
nium chloride from common salt.​

Answer 1

The most suitable method of separation of ammonium chloride from common salt is sublimation.

When ammonium chloride is heated, it gets converted into ammonia (NH₃) and hydrochloric acid (HCl). The chemical reaction of this process can be written as:

NH₄Cl(s) => NH₃(g) + HCl(g) .

Common salt (also known as sodium chloride), on the other hand, does not undergo sublimation.  

Thus, if we heat a mixture of ammonium chloride and common salt, the former will convert to the gaseous phase, while the common salt will be left over as solid. The gases can be collected and cooled to obtain ammonium chloride; thus obtaining the two salts separately.
