Abstract

The static (relative) permittivity of aqueous electrolyte solutions at 25 C, ε(ω = 0) where ω is the frequency of the external field, has been obtained from the literature. The limiting dielectric decrements δ = - lim(c → 0)dε/dc, where c is the electrolyte concentration (≤ 1 mol·dm^-3), are tabulated. The most appropriate additive individual ionic δ _i values are derived. The effect of ion pairing in the solutions is briefly discussed.
