Application of the Specific Ion Interaction Theory to the Ionic Strength Dependence of Aqueous Dissociation Constants of Naringenin in NaClO4 Solutions

The aqueous dissociation constants of naringenin were obtained from potentiometric and spectrophotometricmeasurements at different ionic strength values and 25 °C. Ionic strength of solution was supplied by NaClO4 inthe range of 0.10-4.0 mol dm-3. The dependence of protonation constant on ionic strength was described bySpecific Ion Interaction Theory (SIT), and the specific interaction parameters of the ionic species weredetermined. The protonation constant values were also calculated at infinite dilution
