WHY IS AMMONIUM CHLORIDE AND SALT REMOVED BY SUBLIMATION
ONLY

Shveta Dua · Accepted Answer

Dear Student,
The following activity explains the methodology of
separating ammonium chloride from common salt by the process of
sublimation Take a mixture of common salt and ammonium chloride in
a china dish Place this china dish on a tripod stand and cover the
dish by inverting a funnel over it The funnel should be plugged on
the top with cotton to prevent the vapours of ammonium chloride
from escaping into the atmosphere Heat the china dish using a
burner

On heating, ammonium chloride sublimes As a
result, ammonium chloride gets separated from common salt and
solidifies on the cold walls of the funnel
Hope this helps
Best Wishes!
