Abstract

Even Swiss rain water is acid. Precipitation contains traces of sulfuric acid, nitric acid, heavy matals, and organic pollutants. As Zobrist and Stumm have shown, based on routine analysis of precipitation, Swiss rain water typically contains about 40-50 microequivalents per litre of acidity, with the exception of Alpine regions. Thus the pH in rain water is presently about 4.3. A pure water sample which is in equilibrium with atmospheric CO sub(2) would contain approximately 20 times less hydrogen ions (pH-5.6).
