Measure The Rate Of A Chemical Reaction Lab
Experiment: 3A
The purpose of laboratory assignment 3 was to measure the rate at which a chemical reaction takes place. For the purpose of this lab we measured the rate a balanced oxidation/reduction reaction between iodine, hydrogen, and bromate ion occurs. The above reaction occurs slowly so we used a coupled iodine clock reaction to measure the rate of the oxidation/reduction reaction because it occurs much faster but is still dependent upon the other reaction. To accomplish this, two mixtures were prepared in separate Erlenmeyer flasks. In the 250 ml flask .010M potassium iodide, .0010M Sodium thiosulfate and distilled water was prepared. A 125 ml flask was also prepared with a mixture of .040M potassium bromate, hydro chloric acid and
