Here's a physics student trying to perform the Belousov experiment, that is the chemical clock that changes its color from red to blue and viceversa.
I've been able to "borrow" the following reactants:
H2S04(sulfuric acid) 1,5M
NaBr03(sodium bromate) 0.08M
CH2(COOH)2(malonic acid) 0.002M
Ce(SO4)2 0.1M
ferroin 0.0003.M
I've tried mixing them but I've seen no oscillations. The original recipe says that Ce2(SO4)3 should be used (Ce3+//Ce4+ is what oscillates). What do you suggest I should do? In what order do I mix the reactants? Is this a bad recipe?
Thanks for your help!
