Question: The best method to separate a mixture of Ammonium chloride and Sodium chloride salt is _______
Options:
Evaporation
Hand picking
Magnetic separation
Sublimation
Sublimation
-Sublimation is a process in which solid changes into the gaseous state without passing through the liquid state.
-Substances like camphor, naphthalene balls, etc, get converted directly into a gaseous form from solid to gas on heating.Â
• Explanation:
-Ammonium chloride goes through sublimation.Â
-The mixture of salt and Ammonium chloride can be separated through sublimation.Â
-The mixture is kept in a flask and heated on a china dish as shown.Â
-The cover is closed by the cotton so that the vaporized Ammonium chloride does not go out.Â
-After some time Ammonium chloride goes through sublimation, and its condensed form can be observed on the walls of the flask.Â
-The salt will remain left on the china dish.Â
🔴Additional Information:
-Evaporation is used to separate salt and water in which water is vaporised.
–Â Magnetic separation is used when on the constituent is a magnetic substance.Â
