Physical and Theoretical


The activity and osmotic coefficients of aqueous NaCI in the NaCl-MgCl2-H2O system at 25, 35 and 45°C and total ionic strengths of 0.5, 1, 2 and 3 were obtained by an EMF method using a sodium ion-selective electrode and an Ag/AgCl electrode. The Harned coefficients and Pitzer binary and ternary interaction coefficients were also determined.
