B/Z recipes

For the Belousov–Zhabotinsky reaction in a Petri-dish (3rd December 2013 post)
I used the following recipe:

6 cm3 0.5M potassium bromate(V), KBrO3
0.6 cm3 6M sulfuric(VI) acid, H2SO4
1 cm3 0.5M potassium bromide, KBr
2.5 cm3 0.5M malonic acid
1 cm3 Ferroin indicator solution (Merck commercial solution for waste water analysis)
I read in another source the Ferroin should be about 0.025M.

One mixes the ingredients in a boiling tube or small beaker sequentially in the order listed above.

Videos for the preparation of this mixture can be found here:

and

For the Belousov–Zhabotinsky reaction in a beaker (8th December 2013 post)
I used the following recipe:

100 cm3 1M sulfuric(VI) acid, H2SO4
2.86g malonic acid
1.04g potassium bromate(V), KBrO3
0.11g cerium (IV) sulfate, Ce(SO4)2.4H2O
0.5 cm3 Ferroin indicator solution (Merck commercial solution for waste water analysis)

A video for the preparation of this mixture can be found here:

I have another recipe for this reaction in a beaker which is slightly different and I am going to try it out. In the animated .gif of the beaker reaction posted on the 8th December there was no green colour visible during the transitions and I’m hoping this second recipe will show a green colour.
