How to fill out qualitative analysis unknown anions

How to fill out qualitative analysis unknown anions:

1. Begin by gathering all necessary equipment and materials, including test tubes, reagents, and a pH indicator.
2. Take a small sample of the unknown solution and divide it into separate test tubes for each test. Label the test tubes accordingly.
3. Start with the preliminary tests to determine the general class of anions present. Conduct tests such as the flame test, hydrogen sulfide test, and carbonate test to identify the potential anions.
4. After obtaining preliminary results, move on to specific confirmatory tests for each potential anion. Follow the appropriate protocols for tests like the silver nitrate test, barium chloride test, and sulphate test to confirm the presence of specific anions.
5. Record the observations and results for each test.
6. Once all tests have been carried out and results recorded, compare the observations with known characteristics of various anions to identify the unknown anion(s) present in the solution.
