2. A student analyzes a sample using the preliminary tests and finds that no precipitate is obtained upon the addition of silver ion but a precipitate is observed on the addition of barium ion. Which individual ion tests should be used to determine the anions present in this sample? 3. In the preliminary tests 3 M HNO, is added to the precipitate of the silver group. If a yellow precipitate remains, what ion is probably present?

Analysis of Common Anions and Their Salts
1. Why do the preliminary tests not help in the identification of nitrate ion?
2. A student analyzes a sample using the preliminary tests and finds that no precipitate is obtained upon
the addition of silver ion but a precipitate is observed on the addition of barium ion. Which individual
ion tests should be used to determine the anions present in this sample?
3. In the preliminary tests 3 M HNO, is added to the precipitate of the silver group. If a yellow precipitate
remains, what ion is probably present?
4. Why can't a fresh sample of unknown solution be used for the individual ion test for sulfite?
