The association of ions in electrolyte solutions at very low concentrationand low temperature is studied using computer simulations and quasi-chemicalion-pairing theory. The specific case of the restricted primitive model(charged hard spheres) is considered. Specialised simulation techniques areemployed that lead to efficient sampling of the arrangements and distributionsof clusters and free ions, even at conditions corresponding to nanomolarsolutions of simple salts in solvents with dielectric constants in the range5-10, as used in recent experimental work on charged-colloid sus- pensions. Adirect comparison is effected between theory and simulation using a variety ofclustering criteria and theoretical approximations. It is shown thatconventional distance-based cluster criteria can give erroneous results. Areliable set of theoretical and simulation estimators for the degree ofassociation is proposed. The ion-pairing theory is then compared toexperimental results for salt solutions in low-polarity solvents. The agreementis excellent, and on this basis some calculations are made for the screeninglengths which will figure in the treatment of colloid-colloid interactions insuch solutions. The accord with available experimental results is complete.
