How about this? From: http://www.tannerm.com/IonSpeeds.htm
Ion speeds and conductivity-the Einstein and Stokes-Einstein equations Movement of an ion through a solution under the influence of a potential gradient (electric field) is the result of the acceleration of the charged particle in the field and the opposing forces of assymetry and the electrophoretic effect. Thus the ion moves at a constant rate determined by a balance of these forces. This leads to the definition of mobility ui of the ion i. Ion mobilities at 298 K in aqueous solution Ion u0(m2s-1V-1) H3O+ 36.3 x 10-8 OH- 20.5 x 10-8 Li+ 4.0 x 10-8 Na+ 5.2 x 10-8 K+ 7.6 x 10-8 Ag+ 6.4 x 10-8 Mg2+ 5.5 x 10-8 Zn2+ 5.5 x 10-8 Cl- 7.9 x 10-8 Br- 8.1 x 10-8 NO3- 7.4 x 10-8 SO42- 8.3 x 10-8 >>> Marshall Dudley <[email protected]> 1/12/2006 9:32:37 AM >>> If you know the ion's mobility it can be figured rather easily from the voltage gradient: http://www.du.edu/~jcalvert/phys/elechem.htm and http://www.ce-mag.com/archive/1999/mayjune/mrstatic.html The velocity of an ion is v = KE, where K is the mobility of the ion in cm/s per V/cm. So if you can find the mobility of a silver ion, it would be very easy to figure. I searched a little but was unable to find any mobiity numbers, but they are probably somewhere if you want to look long enough.
