Abstract

From vapor pressure osmometry data, the activity of water, osmotic coeffs. and mean ionic activity coeffs. of glycine (m = 0.006-3.2 mol/kg-1), L-histidine (m = 0.005-0.23 mol/kg-1), L-histidine monohydrochloride (m = 0.008-0.63 mol/kg-1), glutamic acid (m = 0.004-0.05 mol/kg-1), sodium L-glutamate (m = 0.007-0.6 mol/kg-1), and calcium L-glutamate (m = 0.008-0.6 mol/kg-1) have been obtained in aq. solns. at 298.15 and 310.15 K. The Pitzer equations and the mean spherical approxn. (MSA) are used for theor. modeling.
