BZ Reaction

[Empirical1980]

Is this in real time or speeded up?

[ripetersen]

@Empirical1980 The reaction actually lasted for about 8 hours, this is a time-lapse video.

wtf is this

[MissileExpansion]

@xINiiT12oGeINx My chemistry teacher showed us this today. It's a cycle of chemical reactions that just keeps going around and around.

[dreamy2]

Does it last forever?

[ripetersen]

This sample lasted about 8 hours.

So thats how they did the bonanza theme

[Forsiller]

What's a BZ?

@Forsiller

Belousov-Zhabotinsky

[muserandom]

Science!

[hometowngirl56]

Amazing! Had not heard of Beluzov-Zabotinsky until this week.

Yaiiiii, tripping balls! ^^

30-40 seconds looks like the Stargate effect.

Beautiful

[chizor]

i will pay $100 for a pair of these goggles.

[1skullduggery]

@chizor yeah, you could sit across the table from poker pro greg raymer, with confidence....lol.

[tylerjaye]

i picked the wrong time to give up acid.

[jjgossel]

I'll bet the people who did this experiment are totally sweet

Hi,

 I'm currently a finalist chemistry student and am studying these reactions.

I wonder could you please tell me the recipe for the osciallation of the orange/white reaction.

kind regards.

[ripetersen]

The table doesn't format well here but you'll get the idea.

Volume : Concentration : Chemical : Preparation

8mL : 1.875M : NaBrO3 : dissolved in 1N sulfuric acid

5mL : .5M : KBr : dissolved in 1N sulfuric acid

8ml : 1.875M : 1,4-CHD : dissolved in 1N sulfuric acid

4mL : .025M : Ferroin indicator : stock solution - aqueous

25mL : N/A : 1.6% low temp agarose : .4g agarose/25mL d.i. water

[ArremArr]

In your recent correspondence you gave the recipe for the Orange/white reaction. In all of the various reciipies that I have used, the order of mix and the time between additons of compounds was important. Can you supply all of the necessary details to replecate the reaction shown in the video?

Thanks,

Was this time-lapse? Looks like the solution is evaporating at the end...

[ripetersen]

Yes - this is a time lapse video. 1 frame every 10 seconds, the video images about 8 hours of the reaction. Also you are correct in that the solution does evaporate at the end.

Very nice, I've always been fascinated from Beluzov-Zapotinsky reaction!

[ssampanthan]

Wow, This must be very cutting edge stuff. I can't even find Beluzov-Zapotinsky on wikipedia!!
