Relative hydraulic conductance (
) versus ionic strength for an electrolyte with monovalent cations (A) or divalent cations (B). Properties used: given electrolyte in pure water, 
density of chargeable sites, 
, and pore radius 
nm. The electrophoretic mobilities of the cations (
) are related as follows: 
(see Table II). Anion mobilities have negligible effect on
