N2 - The values of the different terms contributing to the free energy of a polyelectrolyte in ionic solu-tion, calculated according to Manningˊs model are compared with those predicted by the Poisson— Boltzmann (P—B) equation solved for the cell model. On this ground, the limits of applicability of Manning’s model and some of its features are discussed. The comparison confirms the usefulness of Manningˊs model for low charge density polyelectrolytes, while for higher charge densities some care should be used due to the breakdown of the approximations underlying the model.
