text: how can i carry out two experiments to distinguish hydrochloric, sulphuric and citric acid?   pretty simple...  test #1:  chloride id test:  add a few drops of silver nitrate to each solution, in hydrochloric acid a white precipitant will appear.  test #2:  sulfate id test:  add a few drops of barium chloride test soltion to each solution, in sulfuric acid a white precipitant will appear.
