To prove empirically that NH4Cl is a part of ammonium chloride.

In order to experimentally confirm the presence of ammonium chloride in the solution, NH4Cl enters, qualitative reactions can be carried out.

The first reaction is the reaction between ammonium chloride and silver nitrate. As a result of the reaction, a silver chloride salt is formed, which precipitates. The sediment has a characteristic appearance of white curd. Also, as a result of this reaction, an ammonium nitrate salt is formed. The molecular equation of the reaction can be written as follows:

NH4Cl + AgNO3 = NH4NO3 + AgCl.
