HELP DETERMINING POSSIBLE SALTS FROM DATA CONCLUSION. Possible salts: Ammonium nitrate, ammonium sulfate, sodium nitrate, potassium sulfide and barium nitrate. Data: The sample completely dissolves in water and is divided into 3 parts. 1. Adding silver nitrate solution results in a black precipitate that is insoluble in NH3. 2. Heating the sample after adding sodium hydroxide produces a gas with the odor of ammonia and which turns litmus paper blue. 3. Adding sodium sulfate solution results in a white precipitate....
