Small colloids in a uni-univalent aqueous electrolyte are modeled by a four-component solvent primitive model. The symmetric Poisson-Boltzmann theory is used to analyze the system and to calculate the second virial coefficient B2 of very dilute particle suspensions for varying solute and solvent concentrations. The results are compared with some experimental results on B2 of the silicotungstate anion suspension in an alkali halide solution.
