Question

Chemical test to distinguish ammonium chloride and sodium chloride

Answer 1

Seperating sand from NaCl & NH4Cl part 1

To start off, you can add water to the mixture, which will dissolve the chlorides, leaving sand as a precipitate in the solution. The sand can be filtered out. After that I am not sure how to separate the chlorides unless you get the temperature high enough to sublimate the NH4Cl, which I think is in the 600 degree Celsius area.
