Dissociation constants for acetic, benzoic, mandelic and succinic acids have been measured at 298.15K as a function of pressure up to 138.8MPa. The spectrophotometric technique using Bromocresol Green as the optical indicator was employed up to ionic strength of 0.03molkg −1 in aqueous solution. Thermodynamic dissociation constants were calculated with the Davies activity coefficient equation...
It is shown that the activity coefficients of the anions resulting from the dissociation of a weak polyprotic acid can be obtained from titration data. Activity coefficients are determined in terms of the activity coefficient of the undissociated acid. The extracted activity coefficients are also dependent on the pH scale adopted in the titration process and are considered as operational coefficients...
