Measurement and Modeling of Mean Ionic Activity Coefficient in Aqueous Solution Containing NaNO3 and Poly Ethylene Glycol

Potentiometric investigation on {H2O+NaNO3+PEG1500} mixtures were made at T=308.15K, using electrochemical cells with two ion-selective electrodes, (Na+ glass) as the cation ion-selective electrode against (NO3- solvent-polymer PVC) as the anion ion-selective electrode. The mean ionic activity coeff...
