WebPDF Flame Test Lab Activity Key - University Of South Florida. Analysis of this light can be used to identify elements and molecules. In today's lab, we will observe the visible range of light emission. Objectives 1. Perform a flame test to identify the characteristic color of metal ions. 2. Identify the metal ion in an unknown solution. 3. Webcolorful 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.
