Classic AP Requirement #12b—Determination of the Rate of a Reaction and Its Order

Students study the rate of the reaction of FD&C Red Dye No. 3 with sodium hypochlorite using a spectrophotometer. First, students create a calibration curve for the dye. Then they find the order of reaction for each of the reactants by varying the concentration of each reactant individually. Finally, a graphical analysis of the relationship of concentration versus time is used to calculate the rate constant. Includes optional FD&C Blue Dye No. 1 for better absorbance with some colorimeters.  

Complete for 30 students working in pairs. A spectrophotometer or colorimeter is required.


Materials Included in Kit (for 30 students working in pairs): FD&C Red No. 3, FD&C Blue No. 1, sodium hypochlorite solution, syringes.
Additional Materials Required (for each lab group): Distilled or deionized water, colorimeter sensor or spectrophotometer (shared), computer interface system (shared), labeling or marking pens, stoppers to fit test tubes, test tube rack, test tubes, timer, lint-free tissues or lens paper.
Additional Materials Required (for Pre-Lab Preparation): 0.001-g precision balance, pipet bulb, volumetric flasks, volumetric pipets.
