Kinetics of Crystal Violet Fading (Spectrometer)

Students determine the reaction order of crystal violet fading in the presence of sodium hydroxide.

This version of the experiment is conducted with a wireless spectrometer. A calibration curve of crystal violet is generated and optimal absorbance wavelength determined by the student. Crystal violet fading is investigated using different concentrations of sodium hydroxide.
