A student tests two substances: solution $$\(\mathbf{E}\)$$ and solid $$\(\mathbf{F}\)$$. Tests on solution E Solution $$\(\mathbf{E}\)$$ is aqueous chromium(III) bromide. Solution $$\(\mathbf{E}\)$$ is divided into two portions. Record the expected observations. From the tests and observations in Table 3.1 it is not possible to identify the cation in solid $$\(\mathbf{F}\)$$. Give another test that can be carried out to help identify the cation in solid $$\(\mathbf{F}\)$$. ................................................................................................................................................ . ..........................................................................................................................................
