WILL FAN AND MEDAL. What is the chemical composition of acid rain? I just need help with a source thats reliable, I've seen many different answers and not sure which is correct (:

Question

anonymous · Answer

The precursors, or chemical forerunners, of acid rain formation result from both natural sources, such as volcanoes and decaying vegetation, and man-made sources, primarily emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) resulting from fossil fuel combustion.

that doesnt answer my question about the chemical compostion.. isn't the chemical composition the same as the chemical equation? (:

anonymous · Answer

Acid rain is caused by nitrogen oxides and sulfur dioxide produced by both natural processes and the combustion of fossil fuels. Eventually, these oxides react with oxygen and water to give nitric acid and sulfuric acid.

Acid rain" is a popular term referring to the deposition of a mixture from wet (rain, snow, sleet, fog, cloudwater, and dew) and dry (acidifying particles and gases) acidic components. Distilled water, once carbon dioxide is removed, has a neutral pH of 7. Liquids with a pH less than 7 are acidic, and those with a pH greater than 7 are alkaline. "Clean" or unpolluted rain has an acidic pH, but usually no lower than 5.7, because carbon dioxide and water in the air react together to form carbonic acid, a weak acid according to the following reaction:
H2O (l) + CO2 (g) is in equilibrium with H2CO3 (aq)

Carbonic acid then can ionize in water forming low concentrations of hydronium and carbonate ions:

H2O (l) + H2CO3 (aq) is in equilibrium with HCO3− (aq) + H3O+ (aq)
However, unpolluted rain can also contain other chemicals which affect its pH (acidity level). A common example is nitric acid produced by electric discharge in the atmosphere such as lightning.[1] Acid deposition as an environmental issue (discussed later in the article) would include additional acids to H2CO3.
