A sample consists of one or more of the following salts: NH4NO3, Na2SO4, NaNO3, Li2S, Ca(NO3)2. The sample dissolves completely in water, and the solution is divided into three parts. Adding AgNO3 solution to one part gives a black precipitate. Heating the second part with NaOH produces a gas which turned moist red litmus paper blue, and smelled of NH3. The third part gives a white precipitate when mixed with Na2SO4 solution.
