Abstract
The dissociation of glycine in Dimethyl formamide mixtures over the temperature range 293.15-308.15 K has been studied by direct conductance measurements. The acid dissociation at each temperature was investigated at solvent composition (X2) involving 0.141. The conductance measurements enabled the estimation of the degree of the acid dissociation, the molar conductivity of the acid at infinite dilution and the activation energy for the movement of cation and anion ions the solvent mixture at infinite dilution. The resulting data have been used to determine the dissociation constant and the associated thermodynamic functions for the acid dissociation in the solvent Mixture. At any temperature in the range 293.15-308.15 Κ. The pKa, and pKa, increased with increasing temperature.
