Flame test to identify metal ions
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 … WebMetal ions produce colorful flames and different metal ions produce different colors and in a mixture of different ions, the flame test will only show the brighter/more visible flame of the metal ions so one wouldn’t be able to tell which other ion is present in the sample. 7.
