| Abstract: | The reversible cell used in this paper consists of the sodium ion selective electrode and the (Ag-AgCl) electrode.By measuring the electrode potential and using the limited law of Debye-Hückel.The activity coefficients of NaCl in 1,2-propandiol solvent have been calculated at three different temperatures,and some variance regulations of the activity coefficients of NaCl solution have been discussed,according to the solvation theory of electrolyte solutions. |
