Purpose: To determine the reaction order with respect to crystal violet dye. Procedure: Turn on a Spectronic 20 and warm it up for at least 15 minutes. Be sure the wavelength is set to 540nm. When the instrument has warmed up‚ use a clean small test tube from the drawer filled 2/3 with the first NaOH solution that is planned to use‚ as a blank set 0% and 100% transmittance. Take a %T reading every minute for at least 15 minutes so it may be convenient to wait until the room clock’s second
