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