Bellevue College Chemistry Club Experiment: Belousov-Zhabotinsky Reaction

Week One Chem-Club Experiment.
BZ-Reaction; An Oscillating Reduction-Oxidation Reaction.

Steps:

1) Dissolve 9.5g Potassium Bromate in 250mL distilled water to make 0.23M Potassium Bromate

2) Dissolve 8g Malonic Acid and 1.75g Potassium Bromide in 250mL distilled water.

3) Dissolve 2.65g Cerium Ammonium Nitrate in 250mL of 2.7M Sulfuric Acid.

4) To make 2.7M Sulfuric Acid; Pour 75mL of 18M Sulfuric Acid into 250mL distilled water. Then add more distilled water to reach 500mL.

5) To make a 0.50% Ferroin Solution; Dissolve 0.115g Melanterite in 50mL distilled water. Then add 0.23g of 1,10-Phenanthroline.

Hopefully those steps make sense :)

Thanks for this. Works a charm!

[MrConstanto]

very nice!)

thank for your "steps",I do this reaction today and it's amazing!

Incidentally: Boris Belousov discovered this "oscilating mix" while researching blood chemistry and glucose cycle.

ahhh very cool! few years back, my chem teacher mixed his up as a demo for fun. her concoction had more vivid colors, but still had the same cycling. how do you stumble upon these mixtures to discover this???
