Production of hydrogen bromide by bromine methane reactions at .

Hydrogen bromide is a potentially useful intermediate for hydrogen production by electrolysis because it has a low cell potential and is extremely soluble in water. Processes have been proposed to exploit these properties, but among the important issues to be resolved is the efficiency of HBr production from hydrocarbon.

Another safety concern in this experiment is the generation of hydrogen gas during electrolysis. Not only is hydrogen a fire and explosion hazard in itself, but bromine and hydrogen can also react to cause ignition or explosion. This is usually a problem only at high temperatures, but keep them separate just to be safe.
