Rainfall with low ph levels, also known as acid rain, is produced by lightning within thunderstorms and is a frequent risk. clean or unpolluted rain has a slightly acidic ph of about 5.2 but unpolluted rain also contains other chemicals. nitrous oxide present during thunderstorm phenomena, caused by the splitting of nitrogen molecules, can result in the production of acid rain, if it combines with the water molecules during precipitation. nitric oxide is present in the atmosphere and is produced by internal combustion engines. sulfur dioxide is introduced to rainfall through the expulsion of volcanic gases and as the product fossil fuel combustion, turning rainfall into sulfuric acid. livestock production is responsible for almost two-thirds of all anthropogenic sources of ammonia, which contributes significantly to acid rain. acid rain can damage buildings and other external structures. in ecosystems, acid rain can cause deaths of plants and marine life. by increasing the acidity of ...more

Precipitation and Pollution are joined together in the air. Then, the rain falls. Thus, the rain is all polluted, making it acid like.

H2O + CO2 = H2CO3
H2O + SO2 = H2SO3
H2O + NO2 = H2NO3

it is mainly caused by Nitric acid, mostly from gold or silver refinery factories.

Acid rain is a rain or any other form of precipitation that is unusually acidic, i.e. elevated levels of hydrogen ions (low pH). It can have harmful effects on plants, aquatic animals, and infrastructure through the process of wet deposition. Acid rain is caused by emissions of compounds of ammonium, carbon, nitrogen, and sulfur which react with the water molecules in the atmosphere to produce acids. Governments have made efforts since the 1970s to reduce the production of sulfur dioxide into the atmosphere with positive results. However, it can also be caused naturally by the splitting of nitrogen compounds by the energy produced by lightning strikes, or the release of sulfur dioxide into the atmosphere by volcano eruptions.

We should not think about them and thinking about its causes make us to lose interest i living. Better drop the point.

Acid rain is due to dissolved acidic oxides present in the atmosphere.

The term acid rain refers to what scientists call acid deposition. It is caused by airborne acidic pollutants and has highly destructive results.
Scientists first discovered acid rain in 1852, when the English chemist Robert Agnus invented the term. From then until now, acid rain has been an issue of intense debate among scientists and policy makers.

Acid rain is rain consisting of water droplets that are unusually acidic because of atmospheric pollution - most notably the excessive amounts of sulfur and nitrogen released by cars and industrial processes. Acid rain is also called acid deposition because this term includes other forms of acidic precipitation such as snow.
Acidic deposition occurs in two ways: wet and dry. Wet deposition is any form of precipitation that removes acids from the atmosphere and deposits them on the Earths surface. Dry deposition polluting particles and gases stick to the ground via dust and smoke in the absence of precipitation. This form of deposition is dangerous however because precipitation can eventually wash pollutants into streams, lakes, and rivers
Acidity itself is determined based on the pH level of the water droplets. PH is the scale measuring the amount of acid in the water and liquid. The pH scale ranges from 0 to 14 with lower pH being more acidic while a high pH is alkaline; seven is ne ...more

U did not see SHAKTIMAN(TV Serial).
Normally In acid rain, the acid(Like CO2, SO2, NH4 .........) which is available in our Atmosphere are comes With Water.
