SUMMARY
Flame tests cannot reliably identify individual metals in mixtures due to overlapping emission spectra. When multiple metals are present, their characteristic colors can blend, making it difficult to distinguish between them. This limitation is particularly evident with metals that emit similar wavelengths of light. Therefore, while flame tests are effective for identifying single metal ions, they are not suitable for complex mixtures.
