Nernst-Haskell equation

Nernst-Haskell The theory of dilute diffusion of salts is well developed and has been experimentally verified. For dilute solutions of a single salt, the well-known Nernst-Haskell equation (Reid et al.) is applicable ... 

The mechanism of ion transport is altered by the contribution of diffusion. To account for this effect, it is necessary to know the electrolyte diffusivity. The diffusion coefficient (Z>B0) at infinite dilution can be estimated via the Nernst-Haskell equation (Reid et al, 1987) ... 

When electrolytes are added to a solvent, they dissociate to a certain degree. It would appear that the solution contains at least three components solvent, anions, and cations. If the solution is to remain neutral in charge at each point, assuming the absence of any applied electric potential field, the anions and cations diffuse effectively as a single component, as with molecular diffusion. The diffusion of the anionic and cationic species in the solvent can thus be treated as a binary mixture. The theory of dilute diffusion of salts is well developed and has been experimentally verified. For dilute solutions of a single salt, the Nernst-Haskell equation is applicable ...
