Why do we use absorbance to monitor the reaction rate? (in an experiment with crystal violet). Is the correct answer a, b, c, or d? a. Crystal violet is poisonous and cannot be titrated b. Spectrophotometery is an inexpensive method c. Crystal violet and basic phenolphthalein are colored solutions d. All of the above
Half-life reaction of the crystal violet
assume that the reaction is first order in crystal violet and that, for a particular NaOH concentration, k' equals 0.048 min^-1. Use equation 3 to calculate how manyminutes it takes for half of the crystal violet to react. This is the half-life of the reaction.
