The kinetics of discoloration of dye, crystal violet was investigated through pseudo first order kinetic at λmax587 nm. The reaction was depended on [CV] and [OH-]. An inversely proportional relation was observed between ionic strength and pseudo first order rate constant i.e. decrease in rate constant and increase in ionic strength. A plausible association mechanism was provided in agreement with the kinetic and spectroscopic results by calculating activation parameter. Spectrophotometric titration revealed the ratio of consumption of crystal violet to hydroxyl ion which is 1:1.
