Briggs-Rauscher Oscillating Clock Reaction

The reactants change colour from orange to black, like a clock reaction ... then it changes back! And back again ... and so on. Credit goes to Rusty for the inspiring commentary.

Do you want a glass of water? Mmmm pardon, orange juice? Ok, well, a cup of coffee?

I'll never understand the need of people like you to so publicly demonstrate their ignorance. Clock reactions work just as baking a cake works: follow the recipe.

NEVER.DO.THIS.FOR.A.CHEMISTRY.­PROJECT.

It hardly ever works.

And there is no source on the internet that will give you a lab that acually works or is clear enough to understand.

Just do the saltbridge and get the grade.

This is demon magic!!!

so if you put it together it turns black after a while, but when you stir it it becomes blank again. but if you stir it while you mix it it will go: "screw you guys!" and turn yellow and gray.

equilibrium and rate law !!!

[donlaszloo]

It's all up to the ratio. Play around with it :)) Colours and colour times vary with composition.

only thing i kno it is done with malonic acid

[agrippaviar]

it must be black lol do some research

[HellawPeoples]

We did this in chemistry camp, it was so cool!
