WebDilute the 25 ml 2M NaOH to 100 mL 0.5 M and add to the third beaker of crystal violet on the overhead projector. (This run should take 4 times as long.) Alternatively, to save time, set the reactions up to run all at once on the overhead, using crystallizing dishes marked on the bottom with the sodium hydroxide concentration. WebThis report investigates how different concentrations of crystal violet and different concentrations of sodium hydroxide affect the initial rate of reaction for crystal violet hydroxylation, and thus determining the order for each reactant, the rate constant and the overall rate law. The experiment was carried out in several steps.
