Occasional readings of acid rain have revealed a #pH# as low as #2.4#.


See this site. Now I enjoy walking in the rain, but rain with such #pH# would actually burn you. The culprits? Of course they are nitrogen and sulfur oxides whose atmospheric chemistry gives nitrous, nitric, sulfurous, and sulfuric acid.
