Talk:Iodine clock reaction

Complicated?
How complicated is this experiment to carry out?--I&#39;ll bring the food 23:25, 29 November 2006 (UTC)


 * Very. I'm doing it for my A-Level coursework and it's a complete bugger to get right. Especially when you suddenly discover that Potassium Persulphate doesn't dissolve above 0.06 mol dm^-3, and the technicians won't give you Ammonium Persulphate instead.

 * Nah, there are harder things that you could've be doing. They give you Ammonium Persulphate at university :) 129.215.48.48 (talk) 00:30, 3 March 2008 (UTC)

Briggs-Rauscher reaction
There's a rather stubby article at Briggs-Rauscher reaction which needs help, or possibly merging into this one. I've forgotten too much of my chemistry to do much about it. 80.41.65.223 20:06, 16 May 2007 (UTC)

Just wondering...
Shouldn't all these reaction involve the triiodide ion? It was my understanding that iodine and iodide ions alone couldn't form the blue starch complex. 24.197.252.185 02:35, 24 May 2007 (UTC) It doesn't help that some variants mention triiodide but don't show it in the equations. How is someone unfamiliar with this chemistry expected to understand what's going on? — Preceding unsigned comment added by 77.158.7.93 (talk) 13:20, 20 February 2018 (UTC)

Update
The Briggs-Rauscher stub has been expanded. Regarding iodine and iodide, triiodide is in rapid equilibrium with them, so the question is moot. Wrauscher 01:43, 2 July 2007 (UTC)

Reaction orders
Hi, just wondering if we could get info on the order of reaction for each of these reactions? Thanks, 129.215.48.48 (talk) 00:32, 3 March 2008 (UTC)

Video
I have added a video of the reaction (persulfate variation). The reaction as filmed also used Fe2+ as a catalyst to shorten the time taken for the colour change to happen. TheSmuel (talk) 21:52, 18 June 2009 (UTC)

Add the equation
Could someone edit in the equation? It's especially ironic that we have like 3 different variations with chemical equations and all, but the iodine clock reaction is only talked about in two lines with no equation!Techdawg667 (talk) 06:26, 4 November 2009 (UTC)

Other method
I'm just making a note of this for later, but there's a whole other method called the Bray–Liebhafsky reaction which should probably be incorporated in some way. Project Osprey (talk) 23:12, 22 June 2014 (UTC)
