The analytical solution of the sticky-electrolyte model is obtained in the mean spherical/Percus–Yecvick approximation. This model can be used to represent chemical association in electrolytes. As in the case of the simple mean spherical approximation (MSA), the general solution is given in terms of a single scaling parameter Γ, which is now also a function of the stickiness parameters. We obtain analytic expressions for the thermodynamic functions ΔA, ΔP, and ΔEex. These expressions give the correct limits when the charge is zero (Barboy–Tenne) and when the sticky parameter vanishes. A particularly simple form of the thermodynamic functions is obtained in which the expressions are identical to those of the MSA, but with a different value of Γ, which now depends on the sticky interactions.
