Awesome experiments! I got a mere idea, but i don't know if it is worth of! Anyway, my hope is i don't get banned for this, (living a fear life, ..... it) I wanted to know whether it is possible to realize an experiment on ideal reactions of the type, i.e. NaCl + H2SO4 <> Na2So4 + HCl 2NaCl + H2SO4 <=> 2Na2So4 + 2HCl which would go on forever, on proper masses and pure chemicals!
