Hi Ken, OK, I think I figured it out. When the electrode is new and shiny, ions are liberated more at discontinuities, perhaps grain boundaries. These areas grow preferentially since they are rough and have more surface area. Eventually they will grow big enough to eliminate the high, shiny areas and cover the entire electrode. So this means a brand-new electrode actually has higher current density than a well-used one. On the other hand, perhaps the roughness tends to focus the activity to the sharp peaks. If the oxide formation takes place very close to the surface, say within a micrometer or so, the peaks actually may look flat, but have a higher ion density than surrounding areas. This may promote the formation of oxide that eventually grows into visible particles. If the oxide is formed much further out, the variations in ion density should smooth out, and it may not make any difference if the electrode is new or well-used. So I guess the next question is which electrode is best to obtain high ppm? A brand-new one, a well-used one, or it doesn't matter?
