Enthalpies of dilution of aqueous solutions of aliphatic x,y-ionene fluorides and iodides, with x,y being equal to 3,3-, 4,5-, 6,6-, and 6,9-, were measured in the concentration range from 0.1 mol kg-1 to 0.0016 mol kg-1. The results were combined with previously obtained data for ionene chlorides and bromides to discuss the ion-specific and charge density effects in these solutions. The comparison with theoretical results, based on Manning's limiting law and cylindrical cell model founded on the solution of Poisson-Boltzmann's equation, is presented. From measured data we calculated the Gibbs free energy and the entropy changes upon dilution to obtain complete thermodynamic description.
