WebThe reaction of crystal violet with hydroxide is: 3 This reaction can be represented as: CV + + OH-→ CVOH purple colorless The kinetics of this reaction can be monitored with a … WebIntroduction Crystal violet is a common, beautiful purple dye. In strongly basic solutions, the bright color of the dye slowly fades and the solution becomes colorless. The kinetics of this "fading" reaction can be analyzed by measuring the color intensity or "absorbance" of the solution versus time to determine the rate law.
