Hi Any ionic bond will break if the temperature is sufficiently high and in a combustion process you will find many temperature levels if you look at very small sections of the flames. This is for example clearly visible in a camp fire. Camp fires, as any kind of burning of biomass can be sources of small amounts of dioxins and dibensofurans as chlorine is naturally available everywhere in the environment in very small and varying quantities. This is something we have to be observant about when we have to change over to burning of more biomass and in many small plants. Good combustion technology is extremely important. Be carefull with cigarettes. The tobacco plantation might have used insecticides with some chlorine content. Regards Björn Dahlroth

If there is no green flame color, then there is no chlorine present. 3: Remove the wire, and sprinkle some salt on the fire. 4: Replace the wire. If the flame turns green, then the salt was dissociated, and chlorine was liberated.
