Molar conductivities of dilute solutions for the complexes: Co(II)(alanine + valine), Ni(II)(valine + serine), Ca(II)(alanine + serine), Mg(II)(valine + serine) in water were measured in the temperature range from (293.16–313.16K). The ionic molar conductivity (Λ), the association constant (KA), distance parameter (R), and (σΛ) at best fit values were determined by treating experimental data with Lee-Wheaton conductivity equation. Thermodynamic quantities for the ion association reaction were derived from the temperature dependence of KA. The obtained results provide information on ion – ion and ion-solvent interactions.
