Assertion - A mixture of camphor and ammonium chloride cannot be separated by sublimation.
Reason - Camphor on heating sublimes, ammonium chloride does not.
Dear student,
A change of state directly from solid to gas without changing into a liquid state is called sublimation. For example, when ammonium chloride is heated, it changes directly from the solid-state into the gaseous state. Similarly naphthalene balls, dry ice also undergo sublimation.
Both camphor and ammonium chloride undergoes sublimation, hence they cannot be separated by the sublimation method.
Hence, the assertion is correct but the reason is false.
Regards
