An archivist at a school chemistry department finds three unlabelled jars containing metal salts, labelled A, B, and C. To identify the metallic cations present, the archivist performs flame tests on samples from each jar. The observations are recorded in Table 1.
| Salt sample | Observed flame colour |
|---|---|
| A | green |
| B | crimson |
| C | lilac |
Use the information in Table 1 to identify the metal ion present in each salt sample.
