Question

Does anyone know the chemical composition of acid rain?
I'm researching it and everywhere I look it either only talks about the ph scale or makes it really complicated.
I'll fan and medal anyone who helps.
Thanks!

Answer 1

My examples for pollutants were sulfur dioxide and nitrogen oxide if that helps

Answer 2

In the gas phase, sulfur dioxide is oxidized by the reaction with the hydroxyl radical via an intermolecular reaction:
SO2 + OH· → HOSO2·
HOSO2· + O2 → HO2· + SO3
In the presence of water, sulfur trioxide (SO3) is converted rapidly to sulfuric acid:
SO3 (g) + H2O (l) → H2SO4 (aq)

Nitrogen dioxide reacts with OH to form nitric acid:
NO2 + OH· → HNO3

Does this help?

Answer 3

Yeah it helps a a lot thanks!

Answer 4

No problem!
