DescriptionAcidity of rain water is a major concern due to the progressive acidification of soils, its effect of flora and fauna and its corrosiveness to metals. Sulfur dioxide, through chemical transformations and atmospheric scavenging, is thought to be one of the major contributors to the acidity of rainwater. The straightforward oxidation of SO2 to SO4 in the presence of ammonia and metal oxides should lead to a resulting pH higher than what is usually encountered and also to much faster disappearance of SO2 during rain. These apparently contradictory conclusions may be reconciled by a more complete analysis of the reaction system.
