WebJan 22, 2024 · A flame test is a qualitative test applied to determine the identity of metals and their ions in compounds. This can be done by observing the colors of metal ions based on the emission spectrum. On heating, every metal ion has its unique color at a specific wavelength. When metals are heated on flame, their electrons jump to higher energy levels. WebFlame tests are used to identify the presence of a relatively small number of metal ions in a compound. Not all metal ions give flame colours. For Group 1 compounds, flame tests are usually by far the easiest way of identifying which metal you have got.
