High Rates of Metal Dissolution and Salt Precipitation

2 High Rates of Metal Dissolution and Salt Precipitation 

Galvanostatic transient for Ni dissolution in saturated NiClj solution with potential increase after the induction time X and the ohmic drop in pores measured by superimposed fast short additional galvanostatic transients. (From Strehblow, H.-H. and Wenners, ]., Electrochim. Acta, 22,421,1977.) 

s and Cm B 3re the metal ion concentrations at the surface and within the bulk electrolyte, respectively 

D is the effective diffusion coefficient containing a correction for the contribution of migration to ion transport within the electrolyte when only the metal salt and no excess of supporfing electrolyte is present (D = (1 + zm / zj )D)
