Rate of an Iodine clock reaction.
I'm doing my pre lab question and one of them states " When the dark color appears, ��[S2O8 2-] = (1/2) ��[S2O3 2-], where ��[S2O3] equals the initial concentration of Na2S2O3". And it asks, why is that statement true?
The concentration of either of the reactants are not given, so I'm not sure how I will know that it is true. Reaction with the most iodine will end faster than the reaction with the least of iodine... starch is constant at 1? Is that correct or it's the other way around? |

In the iodine clock reaction with S2O3 ion I have found that one of the exponents in the reaction rate is 1.55. Can I round it to 2? Or shoud I write it as a fruction 3/2? I know that reaction rate can be a fraction. But it is a fraction in this case? Thank you! :)
How does the starch work in the clock reaction experiment?
Hey, I have done all the varying concentrations for the experiment and am writing a report at the moment but one thing Im not too sure on is why the reastion has to take place with a dilute acid - Sulphuric Acid - and why does it affect the reaction. Im really not sure, please help? Sian x
In our chem lab we're doing an iodine clock experiment. I need help with my equation KIO3 + NaHSO3 + starch --->? I'm pretty sure I2 is produced but I'm not sure of anything else. I need a molecular equation and a net ionic equation. Please help! Thanks
