Activity of Water and Osmotic Coefficients for Two- and Three-Basic Amino Acid Ternary Solutions

Abstract

Osmotic coefficients of ternary systems amino acid–electrolyte–water; aminoethanoic acid (glycine) + NaCl + H2O; aminoethanoic acid + KCl + H2O; aminoethanoic acid + NaNO3 + H2O; aminoethanoic acid + NaSCN + H2O; aminoethanoic acid + NaCOOCH3 + H2O; (S)-2-aminopentanedioic acid sodium salt (sodium l-glutamate) + NaCl + H2O; (S)-2-aminobutanedioic acid sodium salt (sodium l-aspartate) + NaCl + H2O; (S)-2-aminopentanedioic acid sodium salt + KCl + H2O; (S)-2-aminobutanedioic acid sodium salt + KCl + H2O, are inferred from vapor pressure osmometry measurements performed at T = 310.15 K.
