Question

A mixture of salt and ammonium chloride can be separated by crystallisation.

• A. True
• B. False

Answer 1

The correct option is B

False

A mixture of salt and ammonium chloride can be separated by the sublimation process. Ammonium chloride changes directly from solid to gaseous state on heating. The gaseous form of ammonium chloride can be cooled easily to get a pure solid. Ammonium chloride sublimes whereas salt does not sublime, hence common salt and ammonium chloride can be separated using the process of sublimation.
