Iii chemical kinetics iii1- the iodine clock reaction introduction in this experiment, you will study a reaction that proceeds at an easily measured rate at room temperature: s2o8 2- + 2i - 2so4 2- + i2 persulfate iodide sulfate iodine in the first part of the experiment, the rate equation will be determined by investigating. Techniques of volumetric measurements and titration, stoichiometric application, reaction and qualitative analysis the experiments some aspects of coursework that would contribute to a “c” grade might include: weak development of a theme in experiment 6: solutions and clock reaction 8/22 sec a. Dec 2, 2010 this experiment demonstrates the iodine clock reaction between iodide and persulfate ions, using thiosulfate as the 'clock' after some introduction details, three experiments are performed: studying the effect of concentration to determine the orders of reactants (3:01), studying the effect of temperature to. Nov 7, 2013 hi guys, i'm doing the hydrogen peroxide/ potassium iodide “clock” reaction, but i did the lab last week and it was a big failure the time it took for the blue colour to appear was really fast for my lowest concentration of hydrogen peroxide (which is my independent variable) i can only imagine how it will be.

The iodine clock reaction is a favorite demonstration reaction in chemistry classes two clear liquids are mixed, resulting in another clear liquid after a few seconds, the solution suddenly turns dark blue the reaction is called a clock reaction because the amount of time that elapses before the solution turns blue depends.

Experiment 13: the iodine clock reaction background in this experiment you will study the rate of the reaction between iodide ion, i–, and persulfate (peroxydisulfate), s2o82– the products of the reaction are i2 and sulfate ion write the balanced chemical equation for this reaction in the space provided. Through engineering coursework and construct a small-scale vehicle powered by an unconventional the iodine clock reaction serves as the timed chemical process that stops the car after the reaction the duration of the iodine clock reaction is dependent on the concentration of ki used in the reaction.

Jan 4, 2006 502 kinetics of the persulfate-iodide clock reaction (4 points) in this experiment you will investigate the kinetics of the reaction between persulfate then a change suddenly becomes visible, are known as clock reactions clock reactions often appear in chemistry shows, and many involve iodine, since. Iodine clock reactions there are several reactions which go under the name iodine clock they are all reactions which give iodine as one of the products this is the simplest of them, but only because it involves the most familiar reagents the reaction we are looking at is the oxidation of iodide ions by hydrogen peroxide.

Introductionthe iodine clock reaction was discovered by hans heinrich landolt1 and is mainly used todemonstrate kinetics in chemistry the basis of its mechanism is that two clear solutions of knownconcentrations are mixed together and after a delay, the solution will suddenly turn yellow (or darkblue. @t3chnocide if you know your chemistry and haven't heard about clock reactions, it's not that hard to guess i didn't know they were called clock reactions until recently, but i'd seen this sudden change in iodine/thiosulphate/starch titrations where we were determining initial rate our teacher only thought.
