Question

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

• A. True
• B. False

Answer 1

The correct option is B

False

A mixture of salt and ammonium chloride can be separated by sublimation. Sublimation is a process in which solids change directly into gases without undergoing the liquid state. Ammonium chloride undergoes sublimation leaving the salt behind. Hence the mixture gets separated. The vapours of ammonium chloride can be also collected.
