ABSTRACT
Conductivities for ZnSO4/MgSO4 + sucrose/trehalose + water solutions were measured at 298.15 K. The limiting molar conductivities (L0) and association constants (KA) were derived using the Lee Wheaton conductivity equation. From the obtained conductivity data, the values of the Walden product (L0h0) were also calculated. These parameters have been interpreted in terms of ion ion and ion solvent interactions in aqueous saccharide solutions.
