I put a copper pipe in a tank of water with dissolved iron in it and applied an electric current somthing like 6 volts at 1.5 amp and the pipe was hooked up to the positive terminal. After a couple of days some tourquise or pale green substance formed, i scraped this off and there was a copper colored substance but it was a little darker and washed off to expose the copper below. Iwas wondering if the green was basic copper oxide like in the atmospheric weathering of copper.
