摘要：
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, lambda(0)( HAsp(-), T) and the dissociation constants of aspartic acid, K-2(T) were derived by use of the Debye-Huckel equation for the activity coefficients and the Onsager, and Quint and Viallard conductivity equations.
