Abstract

Conductivity measurements of dilute aqueous solutions of DL-aspartic acid, potassium-DL-aspartate and magnesium-DL-aspartate were performed in the 288.15 to 323.15 K temperature range. The limiting molar conductances of aspartate anions, λ0(HAsp-,T) and the dissociation constants of aspartic acid, K2(T) were derived by use of the Debye-Hückel equation for the activity coefficients and the Onsager, and Quint and Viallard conductivity equations.
