4DescriptionAbstract The conductance values of glycine have been measured in the concentration range of 0.006 to 0.08 mol dm-3 in aqueous and aqueous solutions of hydrotropic agents (viz., sodium bromide, sodium benzoate and nicotinamide) of 0.1, 0.2 and 0.3 wt% at different temperatures ranging from 298.15 K to 313.15 K at an interval of 5 K. The conductance data have been computed by Shedlovsky equation to obtain Λ0m and KA. Based upon the composition dependence of Walden Product, the influence of the hydrotropic agents on the solvation of ions has been discussed. The values of association constant KA are used to obtain the standard thermodynamic quantities, such as ΔG0, ΔH0 and ΔS0, for the association process in the solution. It has been observed that the electronic contribution is totally negligible toward the standard transfer thermodynamic quantities.
