What Are Some Uses for Flame Tests? | Reference

Metal ions emit a specific color when heated, which identifies them in the sample. Flame tests cannot detect all elements, and the test only indies the presence of an element, not its concentration. Flame tests use simple equipment, making them ideal for fieldwork. Geologists use the flame test to identify the presence of metals.
