The Effects of Hydrogen Peroxide Concentration, luminol Concentration, and Temperature on the Luminous Intensity of a Chemiluminescent Reaction

The purpose of our experiment was to determine the effects of hydrogen peroxide concentration, luminol concentration, and temperature on a chemiluminescent reaction by measuring the peak luminous intensity of each trial. We tested each of the three variables at a high, low and standard value. Each trial was run using a 50 mL luminol solution, and a 50 mL reactant solution in a dark area, in this case a box. The peak luminous intensity of the light produced was measured by a photo sensor placed in the box using the Logger Pro software. To begin are analysis, we determined the single factor interactions for each of the variables. We then proceeded to find our two factor and our three factor interaction. From there we found our standard deviation, and doubled it to find all significant factors. We found that while temperature has the most significant effect on the interaction, luminol concentration and hydrogen peroxide concentration had significant effects, as did all two and three factor interactions. To conclude, we found that temperature, luminol concentration, and hydrogen peroxide concentration all have an effect on the peak luminous intensity of a chemiluminescent reaction.
