Testing for Anions
- Tests can be used to identify anions in solutions of unknown compounds.
- If multiple tests are being carried out on the same solution it is important to carry them out in the same order as in the table below
Tests for solutions containing one or more unknown anions
- Ammonia can help distinguish between the silver halide precipitates
- Silver chloride dissolves in dilute ammonia
- Silver bromide dissolves in concentrated ammonia
- Silver iodide is insoluble in concentrated ammonia
