Abstract :The electrical conductivities of glutamic acid complex with [Mninsert ignore into journalissuearticles values(ΙΙ);] was study in different solvents insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(Λο); ,The association constant insert ignore into journalissuearticles values(KA);, distance parameter insert ignore into journalissuearticles values(R);, and standard deviation insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(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 minimuminsert ignore into journalissuearticles values( σΛ);, show the results of analysis that complex ions were separated by solvent molecules insert ignore into journalissuearticles values(SSIP);.The values of insert ignore into journalissuearticles values(KA); , insert ignore into journalissuearticles values(Λο); and insert ignore into journalissuearticles values(R); differ from solvent to another depending on the interactions in solution.The walden productinsert ignore into journalissuearticles values(Λη); for this complexe have been studied in water, methanol and ethanol.
