Abstract :The electrical conductivities of glutamic acid complex with [Mn(ΙΙ)] was study in different solvents (water, methanol, ethanol) in the beginning Kohlrausch equations was used to discover types of electrolyte through plot the relation between equivalent conductivity against the square root of molar concentration at different temperature from (288.16 -313.16) kilven. The plot indicate that complex of amino acid was weakly associated in different solvents and temperatures. The molar conductivity of glutamic acid complex measured by processing the obtained data using the conductivity equation of Lee-Wheaton equation to calculation the Equivalent conductance at infinite dilution (Λο) ,The association constant (KA), distance parameter (R), and standard deviation (σΛ).Thermodynamic information from association and examining the nature of the interaction was obtained and calculation of the standard thermodynamic quantities have be measure.A multi parameter curve fitting procedure is used to give the lowest value of curve fitting parameter (σ Λ) between the experimental and calculated values. An iterative numerical method which was found to be very successful has been used to find the minimum( σΛ), show the results of analysis that complex ions were separated by solvent molecules (SSIP).The values of (KA) , (Λο) and (R) differ from solvent to another depending on the interactions in solution.The walden product(Λη) for this complexe have been studied in water, methanol and ethanol.Keywords : Glutamic acid, Electrical conductivities, Lee-Wheaton equation, Thermodynamic parameter
