Explain with diagrams the process used to separate Ammonium chloride from a mixture of ammonium chloride and potassium chloride.
Answer
Sublimation can be used to separate Ammonium chloride from a mixture of ammonium chloride and potassium chloride.
Process — Take a mixture of ammonium chloride and potassium chloride in an evaporating dish, covered with a funnel plugged with cotton. Heat it slowly as shown below:
Ammonium chloride collects on the inner side of the funnel and is scrapped out easily.
Potassium chloride remains in the evaporating dish and is separated out easily.
