Abstract

Kinetics of oxidation of indigocarmine IC] by bromamine-B in pH 5 buffer medium has been studied at 30 degrees C spectrophotometrically at lambda(max) 610 nm. The reaction is first order with respect to IC] and second order with respect to BAB]. The reaction rate shows an inverse first order on benzenesulphonamide]. Addition of halide ions and Variation of ionic strength of the medium have no influence on die reaction rate. There is a negative effect of dielectric constant of the solvent. Activation parameters have been calculated. Mechanism proposed and the derived rate laws are consistent with observed kinetics.
