Answer 1

Answer:

a)Sodium chloride from its solution in water can be separated by Evaporation. b. Ammonium chloride from a mixture containing sodium chloride and ammonium chloride can be separated by Sublimation. ... Decantation: By using separating funnel, Oil and water form separate layers which are separated by using separating funnel

b)There are way in separating mixtures of chloride salts such as that of sodium chloride and ammonium chloride. It can be done by crystallization, filtration, and sublimation. The easiest method among the three is separation by sublimation. Ammonium chloride sublimes upon heating.
