what is sublimation? explain the process of the sublimation of ammonium chloride
Sublimation
The process in which a solid changes directly into its vapour on heating is called sublimation.
This method is based on the difference between the sublimable and non-sublimable nature of solids.
The mixture of sublimable and non-sublimable substances is heated on an evaporating dish covered with an inverted funnel.
On heating ammonium chloride changes into vapours, which condenses into a solid in neck of the funnel and
common salt left behind in the dish.
