The restricted diffusion method is employed to measure the differential diffusion coefficients of nitric acid in water at 25°C for the concentration range 0.033 to 9.25 molar. The concentration gradients of diffusing solutions are observed by Rayleigh interference optics. Experimental transport data are analyzed within the framework of the concentrated solution theory of electrolytes in order to elucidate the macroscopic transport characteristics of nitric acid in terms of specific binary interactions in solution. The results indicate that the transport properties of nitric acid are largely determined, as in other strong acids, by the hydrogen ion‐water molecule interaction.
