An environmental chemist is analyzing three soil-extract samples, labeled D, E, and F, to identify the specific metal cations present. The chemist performs qualitative chemical tests on each sample and records the observations in Table 1.
| Soil-extract sample | Qualitative test performed | Observation |
|---|---|---|
| D | Flame test | Crimson flame |
| E | Addition of aqueous sodium hydroxide | Red-brown precipitate |
| F | Flame test | Lilac flame |
Identify the metal ion present in each soil-extract sample.
