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.

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.
The air pollutants released from the burning of fossil fuels usually comes back to earth in the form of acid rain. Acid rain is a form of precipitation which has high sulfuric and nitric acids, which can also occur in the form of a fog or snow. Acid rain has numerous ecological impacts on streams, lakes, wetlands and
Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids. [65] Some governments have made efforts since the 1970s to reduce the release of sulfur dioxide and nitrogen oxide into the atmosphere.

Concrete damaged by acid rain. Buildings made of any stone, brick or concrete are susceptible to the same weathering agents as any exposed rock surface. Also statues, monuments and ornamental stonework can be badly damaged by natural weathering processes. This is accelerated in areas severely affected by acid rain. [53]
