Deposition of Acid in Precipitation

1982
From the pH and electrical conductivity measured with the automatic precipitation analyser the fraction of total strong acids in precipitation water is derived. Below a pH value of 4, 3 the dissolved matter is dominated by acid. At higher pH values the acid fraction decreases rapidly.
