Acid rain (or more accurately acid precipitation)[1] occurs when sulfur dioxide and nitrogen oxides are emitted into the atmosphere, undergo chemical transformations and are absorbed by water droplets in clouds. The droplets then fall to earth as rain, snow, or sleet. This can increase the acidity of the soil, and affect the chemical balance of lakes and streams.[2] The term "acid rain" is sometimes used more generally to include all forms of acid deposition - both wet deposition, where acidic gases and particles are removed by rain or other precipitation, and dry deposition removal of gases and particles to the Earth's surface in the absence of precipitation.[3]
Acid rain is defined as any type of precipitation with a pH that is unusually low.[4] Dissolved carbon dioxide dissociates to form weak carbonic acid giving a pH of approximately 5.6 at typical atmospheric concentrations of CO2.[5] Therefore a pH of <5.6 has sometimes been used as a definition of acid rain.[6] However, natural sources of acidity mean that in remote areas, rain has a pH which is between 4.5 and 5.6 with an average value of 5.0 and so rain with a pH <5 is a more appropriate definition.[7]

That makes carbonic acid, the fizz in soda, but sulphur from the combustion of high sulphur coal and oil makes sulphuric acid (H2SO4) which is the main problem of acid rain. It damages trees and plants, and eats away at concrete and stone.
