Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH).Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average.

Diagram depicting the sources and cycles of acid rain precipitation. Freshwater acidification occurs when acidic inputs enter a body of fresh water through the weathering of rocks, invasion of acidifying gas (e.g. carbon dioxide), or by the reduction of acid anions, like sulfate and nitrate within a lake, pond, or reservoir.

Robert Angus Smith FRS (15 February 1817 – 12 May 1884), commonly referred to as Angus Smith, [1] was a Scottish chemist, who investigated numerous environmental issues.He is known for his research on air pollution in 1852, in the course of which he discovered what came to be known as acid rain.
Acid rain-damaged forest in Europe's Black Triangle. Such an increase in sulfate aerosol emissions had a variety of effects. At the time, the most visible one was acid rain, caused by precipitation from clouds carrying high concentrations of sulfate aerosols in the troposphere. [25]
It is a reactant in the atmosphere, where it acts as an aerosol, decreasing air quality and clinging to water droplets, eventually resulting in nitric acid (H NO 3) that produces acid rain. Atmospheric ammonia and nitric acid also damage respiratory systems. The very high temperature of lightning naturally produces small amounts of NO x, NH 3 ...
In 1968 the National Park Service designated Camel's Hump a National Natural Landmark, citing the peak as "an exceptional illustration of the complex anticlinal deformation which formed the Green Mountains". [11] The landmark area consists of approximately 5,300 acres (2,100 ha) from the summit down to 2,500 ft (760 m). [12] [13]
Turów Power Station, a thermal power station in Bogatynia, Poland Effects of acid rain in the Jizera Mountains in 2006. The Black Triangle (German: Schwarzes Dreieck, Lower Sorbian: Carny tsirozk, Upper Sorbian: Čorny trirózk) is the border region between Germany, Poland and the Czech Republic, long characterized by extremely high levels of pollution.
