Acid Rain Equations

Postby Ava Kjos 1D » Mon Dec 03, 2018 8:48 pm

What were the other equations for the cause of acid rain besides the one with carbon dioxide (CO2 + H2O --> H2CO3)? What are some possible options to reduce acid rain?

One equation include sulfur:
S + O2 → SO2
2SO2 + O2 → 2SO3
SO3 + H2O → H2SO4
Sulphur, which comes from burning of coal, reacts with oxygen in the air to form sulfur dioxide (an acidic oxide). Sulfur dioxide is then oxidized, forming sulfur trioxide. The sulfur trioxide reacts with either hydrogen atoms or water in the air, then becomes sulphuric acid, which falls back down to earth as "acid rain."

Another equation includes nitrogen:
N2 + 2O2 → 2NO2
2NO2 + H2O → HNO3 + HNO2
2HNO2 + O2 → 2HNO3
Nitrogen gas reacts with oxygen in the air, forming nitrogen dioxide (an acidic oxide). Nitrogen dioxide reacts with water to form a mixture of nitric acid and nitrous acid. Nitrous acid can further react with oxygen, forming more nitric acid, which can also fall back as "acid rain."

Possible ways to reduce acid rain is to avoid using fossil fuels for energy, such as walking or biking instead of driving or commuting. More renewable energy sources, like solar and wind power, can also be used.
