A polyelectrolyte solution contains the salt of a polyion, a polymer comprised ofrepeating ionized units. In dilute solutions, a substantial fraction of sodium ions arebound to polyacrylate at concentrations where sodium acetate exhibits only dissociatedions. Thus counterion binding plays a central role in polyelectrolyte solutions .Close approach of counterions to polyions results in mutual perturbation of thehydration layers and the description of the electrical potential around polyionsis different to both the DebyeHuckel treatment for soluble ions and the GouyChapman model for a surface charge distribution, with Manning condensation ofions around the polyelectrolyte ....
