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. WebNov 21, 2024 · Bismuth burns with a blue flame and clouds of yellow oxide when heated in air, according to Robert E.
