Abstract
The tracer diffusion coefficients of sodium-aa-chloride were determined as function of magnesium chloride concentrations in aqueous solutions(10(-4).. . 1 mol dm(-3)) at 25 degrees C. Closed capillary method was used in experi ments. The most accurate method to calculate the tracer diffusion coefficie nt from an infinite series solution was further developed. The Onsager limi ting law was verified to the tracer diffusion of (NaCl)-Na-22 in aqueous ma gnesium chloride in low concentration region.
