#2"SO"_2 + "O"_2 + 2"H"_2"O" rightleftharpoons 2"H"_2"SO"_4#

#4"NO"_2 + "O"_2 + 2"H"_2"O" rightleftharpoons 4"HNO"_3# Pure rainwater is already acidic due to carbon dioxide (#"CO"_2#) in the air dissolving in the rainwater and reacting according to the following equation. #"H"_2"O" + "CO"_2 rightleftharpoons "H"_2"CO"_3^# Acid rain is caused additionally by having large amounts of sulfur dioxide (#"SO"_2#) and nitrogen oxides (#"NO"_x#) from the atmosphere dissolve into the rainwater. Sulfur dioxide is produced primarily from burning of fossil fuels that contains sulfur. It gets oxidized by molecular oxygen present in air to produce sulfur trioxide (#"SO"_3#), according to the following reaction. #2"SO"_2 + "O"_2 -> 2"SO"_3# Rainwater then dissolves the sulfur trioxide that was created. #"SO"_3 + "H"_2"O" rightleftharpoons "H"_2"SO"_4# The two steps are combined to give the overall response. #2"SO"_2 + "O"_2 + 2"H"_2"O" rightleftharpoons 2"H"_2"SO"_4# Nitrogen dioxide results from combustion using air (which 99% is made up of #"N"_2# and #"O"_2#) as oxidants. It reacts in water to form a equimolar nitrous (#"HNO"_2#) and nitric acid (#"HNO"_3#) solution. #2"NO"_2 + "H"_2"O" rightleftharpoons "HNO"_2 + "HNO"_3# However, nitrous acid decomposes rapidly to regenerate nitrogen dioxide and water, while at the same time producing nitric oxide (#"NO"#). #2"HNO"_2 -> "NO" + "NO"_2 + "H"_2"O"# Although it does so more slowly, atmospheric oxygen can oxidize the nitric oxide that is produced back into nitrogen dioxide. #2"NO" + "O"_2 -> 2"NO"_2# As a result, the total equation when the three reactions are combined is #4"NO"_2 + "O"_2 + 2"H"_2"O" rightleftharpoons 4"HNO"_3# All the acids produced in the above reaction will dissociate in water to give #color(red)("H"_3"O"^{+})#, which is why the pH decreases. #"H"_2"CO"_3 + "H"_2"O" rightleftharpoons "HCO"_3^{-} + color(red)("H"_3"O"^{+})# #"HNO"_3 + "H"_2"O" -> "NO"_3^{-} + color(red)("H"_3"O"^{+})# #"H"_2"SO"_4 + "H"_2"O" -> "HSO"_4^{-} + color(red)("H"_3"O"^{+})#

undefined The chemical formula for acid rain typically involves sulfur dioxide (SO2) and nitrogen oxides (NOx) reacting with water (H2O) in the atmosphere to form sulfuric acid (H2SO4) and nitric acid (HNO3). Therefore, the overall chemical formula for acid rain can be represented as:

H2SO4 + HNO3
