The transference numbers for aqueous solutions of potassium acetate at 25°C have been determined by the moving boundary method for the concentration range 0.01 N to 0.25 N. Two different types of cell and two different methods of measuring the number of coulombs were employed. Up to 0.16 N the transference numbers can be represented by the Shedlovsky-Longsworth equation within ±0.05 percent, and lead to a transference number for the cation at infinite dilution of 0.6428, in close agreement with that obtained from the limiting ionic mobilities.
