Abstract
The acidity of precipitation in rural, forested areas of the northeastern United States is dominated by the strong mineral acids: H2SO4 and HN03. Weak acids have a negligible effect on the measured acidity (pH) of precipitation. These conclusions are based on total acidity titrations and detailed analysis of organic and inorganic components in precipitation.
