Abstract

In different incident precipitation and throughfall samples, it is shown that the CO₂-acidity (base neutralizing capacity up to pH 8.3) can be twice the H₃O+ concentration. This fact can be explained only by the existence of weak acids (with the exception of H₂CO₃*). The buffer capacity was determined by using an exact acid/base-buffer-titration. Assuming the existence of only one weak acid, the concentration and strength were calculated.
