Conductivities of CuSO₄ and CdSO₄ in Sucrose/Trehalose−Water Systems at 298.15 K

The conductivities of CuSO₄ and CdSO₄ in aqueous disaccharide (sucrose and trehalose) solutions were measured together with the densities, viscosities, and relative dielectric constants of the aqueous disaccharide solutions at 298.15 K. The limiting molar conductivities (Λ₀) and association constants (K_A) were derived from the Lee−Wheaton conductivity equation. From the obtained conductivity data, the values of the Walden product (Λ₀η₀) were also calculated. The ion−ion and ion−solvent interactions are discussed.
