Abstract

Conductance measurements of aqueous solutions of succinic acid and of di-sodium succinate were performed from 278.15 to 308.15 K and the limiting conductances lambda-0 (1/2 Succ2-) are reported. The Walden product is independent of temperature: lambda-0 (1/2 Succ2-) . eta(T) = 0.503 +/- 0.001. The salt conductances closely obey the Onsager limiting law. The evaluation of the equilibrium constants for the primary and secondary steps of dissociation, K1 and K2, and the limiting conductances of the hydrosuccinate ion, lambda-0 (HSucc-), are discussed using the Quint and Viallard conductance equation.
