The mixing effect of glycine with sodium chloride from activity coefficients investigations at T = (303.15 and 313.15) K
The mixing effect of electrolyte and aminoacid on activity coefficients in NaCl+Glycine+Water mixtures, for molality of glycine and NaCl up to 2 mol kg-1 was investigated. The activity coefficients at (303.15 and 313.15) K of NaCl and glycine in aqueous solutions were measured using potentiometric method. The obtained experimental data were fitted by Scatchard-Prentiss and Roberts-Kirkwood equations. The mean ionic activity coefficient of NaCl decreases

Activity coefficient values for NaCl and glycine are determined by studying their aqueous mixtures at different electrolyte and glycine concentrations. The mean ionic activity coefficient of NaCl was calculated from cell potential measurements: Na-ISE/NaCl (mNaCl); glycine (mGly)/Ag/AgCl. Measurements were made over the concentration range of (0.005 to 2) mol • kg-1 glycine and of (0.05 to 2) mol • kg-1 NaCl at temperatures (298.2, 308.2, and
