Acid rain - Wikipedia
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. [1][2] The more acidic the acid rain is, the lower its pH is. [2] Acid rain can have ...
What is Acid Rain? - US EPA
Acid rain, or acid deposition, is a broad term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms. This can include rain, snow, fog, hail or even dust that is acidic. What Causes Acid Rain?

Acid rain | Definition, Causes, Effects, & Formulas | Britannica
Acid rain, precipitation possessing a pH of about 5.2 or below mainly produced from the emission of sulfur dioxide (SO2) and nitrogen oxides (the combination of NO and NO2). Acid deposition can reduce the pH of surface waters, lower biodiversity, and increase the susceptibility of plants to disease and other stressors.

Acid rain causes, effects, and solutions | National Geographic
Acid rain is any form of precipitation that contains high levels of nitric and sulfuric acids. First coined by Scottish chemist Robert Angus Smith in 1852, acid rain can also occur in the form of ...
Acid Rain: Definition, Causes, Effects, and Solutions
Acid Rain What is Acid Rain? Acid rain, also called acid deposition, is a broad term for any form of precipitation with high concentrations of sulfuric and nitric acids. According to the Environmental Protection Agency (EPA), deposition can be wet such as in rain, fog, snow, mist, or dry, as in dust, gas, and smoke.
Acid Rain and Water | U.S. Geological Survey - USGS.gov
Depending on where you live, maybe you've heard of acid rain. Now, acid rain is not pure acid falling from the sky, but rather it is rainfall or atmospheric moisture that has been mixed with elements and gases that have caused the moisture to become more acidic than normal. Pure water has a pH of 7, and, generally, rainfall is somewhat on the acidic side (a bit less than 6). But, acid rain can ...
