Mar 3, 2010 - Hi, thanks for this video.I am studying this reaction for a chemistry investigation, and am having some trouble dissolving Potassium Iodate.At the moment, I have had it in about 50C water on a magnetic stirring plate for about 1hr45 and have a pinkish solution with lots of sediment. Should it take this long?How can I make it dissolve faster?

haoyuan93 Says:

Mar 10, 2010 - well u need hot water to rapidly dissolve potassium iodate.boiling or close to boiling water is recommended.

Jul 2, 2010 - haha did you have to pour everything in so slowly? I need to pee now.

Dec 10, 2010 - Amazing video! I'm going to try this myself in the near future, it's an extremely interesting reaction. Your explanation was excellent. My favorite part was actually right at the end, when it looked like the thiosulfate had cleared it up, but then the iodine came back with a vengeance :) Keep up the great work!

Jan 18, 2011 - Could you please post your procedure, or maybe a link to one that is the same as yours?!PS, If youre going to try this, make sure you use the boiling water, it doesnt work otherwise.

Mar 23, 2011 - I tried out differant methods of measuring/recording oscillation periods for this reaction once for a project: it worked fine in general, but a temperature probe I used showed almost no fluctuations in temperature. Was it something I effed up on, or should their be little change between oscillations?

Aug 27, 2011 - Jcool! ust a shame it only goes on for 5 minutes.

Dec 31, 2011 - Hello there,I'm going to be running a stand for the RSC at BT young Scientists in Dublin and I'd like to show this. Is it possible for the solutions A, B and C to be prepared in advance and are they safe enough to transport? Also is this OK to be done without fume hood ventilation? Is there any way to make is last longer than about 5 minutes?Kind Regards,Sonia Olejarz

Feb 25, 2012 - Another youtuber said that they never seen the reaction so clearly until now. Why? Is it due to impurities or something else?

mxlauve Says:

May 10, 2012 - very nice. I did the same reaction for my p-chem project, but it didn't turn out as nicely as this one did. After watching this I think I should have added a bit more hydrogen peroxide
