Abstract Four diffusion coefficients for one composition of the system H2O-Bu4NBr-HBr were obtained at 25°C. The value of (D 12)v was negative and large as expected from the primary charge effect. However, the value of (D 21)v was also negative despite the fact that the primary charge effect predicts a positive value. This was interpreted to be a consequence of a large negative value for δ ln y2/δC1 which overshadows the primary charge effect.
