Question

Ammonium chloride and salt is separated by the process of ______________. The volatile component in this case is ______________.

• A. sublimation, salt
• B. centrifugation, ammonium chloride
• C. sublimation, ammonium chloride
• D. centrifugation, salt

Answer 1

The correct option is C

sublimation, ammonium chloride

Ammonium chloride and salt is separated by the process of sublimation. The volatile component in this case is ammonium chloride.
Sublimation is defined as the transition of a substance directly from the solid state to the gaseous state without under going through the intermediate liquid state. Ammonium chloride is sublimable and salt is non-sublimable, therefore we use sublimation to separate them.
