when was the term acid rain first used?
the 17th century
the phrase "acid rain" was first used by scottish chemist robert augus smith in 1852. the ph of rain varies, especially due to its origin. on america's east coast, rain that is derived from the atlantic ocean typically has a ph of 5.0–5.6; rain that comes across the continental from the west has a ph of 3.8–4.8; and local thunderstorms can have a ph as low as 2.0. rain becomes acidic primarily due to the presence of two strong acids, sulfuric acid (hso) and nitric acid (hno). sulfuric acid is derived from natural sources such as volcanoes, and wetlands (sulfate reducing bacteria); and anthropogenic sources such as the combustion of fossil fuels, and mining where hs is present. nitric acid is produced by natural sources such as lightning, soil bacteria, and natural fires; while also produced anthropogenically by the combustion of fossil fuels and from power plants. in the past 20 years the concentrations of nitric and sulfuric acid has decreased in presence of rainwater, which may be due to the significant increase in ammonium (most likely as ammonia from livestock production), which acts as a buffer in acid rain and raises the ph.
