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....

Sodium carbonate is added to the tea mixture, in part, to form the sodium salt of the gallic acid present in tea. This salt is much more soluble than caffeine in water, and it is much less soluble than caffeine in dichloromethane. (1) Suggest why the sodium salt of gallic acid should be highly soluble in water. (2) What would happen to the gallic acid in the tea if no sodium carbonate solution were added during the procedure described in...
