Specification Point 9.1C:
Explain why the test for any ion must be unique
- Ions are charged atoms, molecules or particles.
- The chemical identity of ions is determined using various types of tests, depending on the charge, state and nature of the ion.
- The tests are investigative in nature, and used to identity the composition of an unknown compound by identifying the ions present.
- Each test must therefore be unique, that is to say that the test gives an easy-to-observe result that is specific to the ion present.
- If this isn’t the case then the ion tests will not serve their purpose.
