Acid Rain

Pure water has a pH of 7.0 (neutral); however, natural, unpolluted rainwater actually has a pH of about 5.6 (acidic).[Recall from Experiment 1 that pH is a measure of the hydrogen ion (H+) concentration.] The acidity of rainwater comes from the natural presence of three substances (CO2, NO, and SO2) found in the troposphere (the lowest layer of the atmosphere). As is seen in Table I, carbon dio...

Acid Rain in Wisconsin

While pure rain is naturally slightly acidic, the higher level of acidity in acid rain makes it a threat to plant and aquatic life and to some manmade materials and structures. The slight natural acidity of pure rain is the result of carbon dioxide in the air dissolving in water to produce a weak carbonic acid solution. This natural acid in rainfall and snowmelt is partly responsible for the lo...

Environment Agency - Acid rain

Once the acidic gases have been emitted to the atmosphere they can be transported over large distances. Hydrogen chloride is highly soluble and is deposited close to source areas, whereas sulphur dioxide and nitrogen oxides are relatively insoluble (at atmospheric concentrations) and are therefore usually transported much further from the source before being deposited. For example, around 90% o...

Acid Rain Watershed Interactions Revisited

Until recently, the scientific consensus has been that acid-rain-watershed interactions are those of processes which predominate in deep, well-drained mineral soil and the waters derived from them. In such watersheds alkaline minerals dissolve to naturally impart alkalinity to surface waters and normally acid components in rain would be neutralized. Furthermore, the sulfate of the sulfuric acid...
