Flame test technicians notes
WebThe flame test technique is very quick and simple method used in qualitative chemistry analysis to identify some of the metal ions. WebThe test is based on the reaction of chlorine with copper compounds at the high temperatures found in burner flames. These conditions produce excited, green-coloured copper atoms or ions that cause the normally colourless (or very slightly blue) flame to flare brilliant green (or sometimes blue-green). Procedure
