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.

[1] [2] These gases contribute to the formation of smog and acid rain, as well as affecting tropospheric ozone. NO x gases are usually produced from the reaction between nitrogen and oxygen during combustion of fuels, such as hydrocarbons, in air; especially at high temperatures, such as in car engines.
Here are five reasons why freezing rain is the worst preciptation type: 1. It Could be A Silent, Invisible Killer.
At high concentrations, gaseous SOx can harm plants by damaging foliage and decreasing growth. SO2 and other sulfur oxides can contribute to acid rain. [83] Further oxidation of SO 2, usually in the presence of a catalyst such as NO 2, forms H 2 SO 4, and thus acid rain is formed.
The water is expensive, possibly dangerous, and insulting to people struggling for clean, treated water all over the world. So save yourself the $16 and enjoy the clean water we already have ...
Blood rain; Cold drop (Spanish: gota fría; archaic as a meteorological term), colloquially, any high impact rainfall event along the Mediterranean coast of Spain; Drought, a prolonged water supply shortage, often caused by persistent lack of, or much reduced, rainfall; Floods. Flash flood; Rainstorm; Red rain in Kerala (for related phenomena ...
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
