The enthalpies of solution have been measured for glycine in some sodi
um halide solutions at 298.15 K. The enthalpic interaction parameters
h(xy), h(xxy) and h(xyy) of glycine with the sodium halides have been
evaluated. The dependences of the enthalpic interaction parameters on
the ionic size of the electrolytes have been discussed with respect to
electrostatic and structural interactions.
