Investigation of di-p-sulphonic acid aniline phosphate was carried out by using "Allen's" modified method of colorimetry in acid medium from 0.1 to 7.0 mol dm(-3) at 98 degrees C in 20% dioxane-water mixture (V/V). Ionic strength data exhibit different contribution of neutral species and presence of acid catalysis. Theoretical rates estimated from 2nd empirical term of Debye-Huckel equation have been found in close agreement with experimental rates. ionic strength, temperature, solvent of kinetic studies are provided, to identify the reactive species. Molecularity and bond fission are also discussed in terms of Zucker-Hammett hypothesis, Hammett acidity functions, Bunnett and Bunnett-Olsen parameters and isokinetic relationship.<
