Chemistry / Re: What is the chemical equation for the rusting reaction of iron in salt water?

Thank you, mate. Got another question, how about if I wrap piece of copper wire around the iron? My experience is the iron would rust faster and I assume that's because iron is more reactive than copper, so it will release electrons easier:
Fe -> Fe2+ + 2e-
But where do the electrons go? Usually, I'd say:
Cu2+ + 2e- -> Cu
That would bring me to the copper's involvement in all of this, but where did the copper ions come from?
