Diffusivity, mass nonelectrolytes

The diffusive and convective terms in Eq. (20-10) are the same as in nonelectrolytic mass transfer. The ionic mobility Uj, (g mol cm )/(J-s), can be related to the ionic-diffusion coefficient D, cmVs, and the ionic conductance of the ith species X, cmV(f2-g equivalent) ... [Pg.19]

This gives the mass of solute diffused per unit time through a cross-section S, in terms of the concentration gradient dcfdx in the direction x perpendicular to (he cross section. D is a constant for (he given solute and solvent at a given temperature, and is called the diffusion coefficient. For any one pair of substances. D is found to be proportional to the absolute temperature. It should be stated that these statements apply only to nonelectrolytic solutions. [Pg.494]
