Does that mean if you have acid rain, it reduces back to iron?

  Acid rain oxydizes. Reduction is the oposite chemical reaction.

    Ah, thanks. Then I misremembered my high school chemistry from 25y ago. I thought rust (the verb) is oxidation and that when you add an acid, it would be reduction (to get back the iron).

      Acid / base and oxidize / reduce are mostly orthogonal. Acid / base is about moving around protons while oxidize / reduce is about moving electrons.

      "Acid" is from Latin acidus (sour, sharp, tart) by way of French. "Oxygen" is a word invented in 1777 by Antoine Lavoisier, from the Greek oxys (sharp, acid): same thing! Lavoisier also invented "oxide" from ox(ygène) + (ac)ide.
