Description
Acid rain is defined as precipitation (rain, snow, or sleet) having a PH below 5.6 . Nonpolluted rain has a pH of about 5.6 due to the dissolved Carbon dioxide that naturally forms some Carbonic acid. More deleterious pollutants, such as Sulfur dioxide and Nitrogen oxides, are produced from combustion sources, coal smoke, chemical manufacturing, and smelting. Water vapor condenses on the pollutant particles and reacts to form acids. This acidic precipitation is very detrimental as it can kill trees, destroy freshwater animals, corrode metal, and dissolve carbonaceous stones (Limestone and Marble).
