JCE Classroom Activity
Rain, Lakes, and Streams - Investigating Acidity and Buffering Capacity in the Environment
Judith A. Halstead
Skidmore College, Saratoga Springs, NY 12866
Cover
December 1997
Vol. 74 No. 12
p. 1456A
Abstract
Rain and snow are naturally somewhat acidic because of carbon dioxide in the atmosphere. As rain falls through the air, carbonic acid is formed, resulting in a typical pH of clean natural rain of approximately 5.6. Atmospheric pollutants can lower the pH even more. The effect of acid rain on lakes and streams depends on their natural buffering capacity.
