This practical gets students to measure the rate of reaction when a thiosulfate solution is mixed with hydrogen peroxide.
The resource includes a brief background to the experiment, a sheet to record data and some instructions for the Technician to help make up the solutions.
This resource can be used for younger students to improve their experimental technique and interpretation and graphing skills (leave out the chemical equations) or for A2 Cambridge, Honors or AP students who wish to measure more detailed reaction kinetics.
Some errors were found and have since been addressed (2016)
Key words: kinetics, reaction rate, collision theory, iodine clock reaction, experiment
