Answer 2

Answer:

Ammonium chloride is first separated from the mixture by heating. The technique of sublimation is used.

Next, from a solution of salt and sand in water. Sand is insoluble in water and can be separated by filtration.

The solution now contains only salt and water. Salt can be separated by heating the mixture as only salt will remain in the dish and water will be evaporated.
