The kinetics of the reaction of the food colorant FDandC Blue #1 with sodium hypochlorite (Clorox) is described in a student-designed experimental format. In this format, students are guided- by means of questions- to make decisions regarding concentration of reagents, choice of equipment, and actual laboratory procedures to be followed. This forma...

... Of the four laboratories that used bleach plus a food dye, three determined the pseudo 18 order of both the dye and bleach. 12,13,15 The lab using sodium hydroxide and phenolphthalein 16 determined the order of both reactants, whereas two laboratories only determined the order of the dye 14 or crystal violet. 17 In this respect, the kinetics lab addressed in this paper is similar to previous ones, though both the pseudo order 18 of the blue food colored solution and bleach are determined. ...
