| Abstract: | Conductivity measurements on aqueous solutions of D-tartaric acid, L-tartaric acid, andmeso-tartaric acid were performed in the temperature range 278.15–308.15 K. The equivalent limiting conductivity of the bitartrate anion, λ°(HTar-), is evaluated with regard to the primary and secondary steps of dissociation of the acids in aqueous solutions by use of the Quint and Viallard equation for unsymmetrical electrolytes. |
