Question

What happens to pure ammonium chloride during sublimation of ammonium chloride?

Answer 1

Hint :The inorganic compound ammonium chloride ($NH_4Cl$) is a white crystalline salt that is extremely soluble in water. Ammonium chloride solutions are moderately acidic. The natural, mineralogical form of ammonium chloride is known as sal ammoniac. Condensation of coal-derived gases frequently forms the mineral on burning coal heaps.

Complete Step By Step Answer:
In the form of a sublimate, pure ammonium chloride is gathered on the inner sidewalls of the funnel. A substance's ability to transition straight from solid to gas or vice versa is known as sublimation. These compounds are referred to as sublime. Cover a china dish with a combination of ammonium chloride and salt and an inverted conical clear funnel. Place a cotton stopper at the opposite end of the funnel to prevent vapours from escaping. Place the ceramic dish on top of a burner now. Because ammonium chloride is sublime after heating, it will transform to vapour immediately. This vapour will condense again in the funnel's higher, colder section, forming solid ammonium chloride. The sublimation process may be used to separate the combination of ammonium chloride and salt in this way. When heated, ammonium chloride transforms from a solid to a gas. As a result, when ammonium chloride is heated, it turns into white vapours. Ammonium chloride in gaseous form may be readily cooled to create a pure solid. Because ammonium chloride is sublime, it will convert instantly to vapour after heating, and this vapour will condense at the funnel's higher, cooler section to create solid ammonium chloride. This is a sublimation process in which a solid is transformed straight to gas. It's a reversible process. Ammonium chloride heating is an endothermic process.

Note :
Sublimation is the process of converting stuff from a solid to a gaseous state without passing through a liquid state. Sublimation is the term used by those of us who are interested in the water cycle to describe the process of snow and ice converting into water vapour in the air without first melting into water.
