The Briggs-Rauscher Oscillating Color Change Reaction

THIS. IS. AWESOME.

Don't ask why it happens 'cause WARNING! Cheem Chemistry Alert. Google it if you must, but at the risk of brain overload.

So, just enjoy the colours:)

In essence, colourless solution + yellow solution + ferroin indicator = a mixture that just keep changing colour!!

I'm sorry I'm unable to edit out the random conversation:P

The colours looks alluring.

dont try to understand this reaction since its VERy complicated. ive warned you

@rhodio1968 What is the difference between the two reactions?

[rhodio1968]

I think that this is NOT the Briggs-Rauscher Oscillating Reaction, but this IS the Belousov-Zhabotinsky Oscillating Reaction: Malonic Acid (COOHCH2COOH), Potassium Bromate (KBrO3), Sulphuric Acid (H2SO4) and Potassium Bromide (KBr). The color indicator is Ferroin. The composition is easy to find on the web. Look up "Belousov-Zhabotinsky Oscillating Reaction".

Enjoy!!! :-D

please can the author of the video post the REAGENTS and QUANTITIES? I would really like to perform this experiment in a demonstration lecture. Thanks!

[THATxKIID]

does anyone know where i can find the directions and materials needed for this experiment? i would appreciate it very much...message me with a link ASAP please, and thank you

@bowtech616 Yeah I figured that after I commented. First I thought they added other stuff to the solution (while still being BR) but that isn't even possible. So yus this is very different. Still one hella awesome reaction to use as a demo for people that don't like chemistry.. I mean chemistry is awesome!! o.o

[bowtech616]

@Phenylbutanol This isnt the Briggs-Rauscher oscillating reaction. This one contains completely different components, starch isnt even used in this reaction.

@nickharvey7

Do you really think that there is only water in the beaker? = lol

[wrauscher]

@Phenylbutanol The color changes seen here are those of the related Belousov-Zhabotinskii reaction, with Ferroin (Iron phenanthroline) indicator. Check out any video of that reaction. Smart question!
