Flame color for metal ions

WebBased on the results of the flame test, it was evident that the main ions responsible for the color intensity of the flames are the metal cation. Since a specific energy is needed to radiate specific light color for every cation, all compounds containing similar metal cations have the same flame colors observed. POST LABORATORY QUESTIONS. 1. WebClick the Flame w/Cobalt button and record your observations in the same table. Drag the K+ test tube to the metal stand to exchange it with the Na+. Perform a flame test on K+ with and without cobalt glass. Record your observations in the data table. For the other four ions, perform a regular flame test only. Do not use the cobalt glass.
