Belousov–Zhabotinsky Reaction

A really cool reaction to see and a great example of non-equilibrium reaction dynamics.



This is an example of a free radical reaction with the following reaction mechanism:

HBrO3 + HBrO2 -> 2BrO2 (radical) + H2O

H+ + 2BrO2 (radical) +  Fe(phen)32+ -> Fe(phen)33+ + HBrO2

HBrO2 + H+ + Br- -> 2HOBr
