Formation of Sulfuric Acid
Kelter, Carr, Scott, Chemistry A World of Choices 1999, page 302
SO2(g) + H2O(l) H2SO3(aq)
2SO2(g) + O2(g) 2SO3(g)
SO3(g) + H2O(l) H2SO4(aq)
SO2(g) + H2O2(l) H2SO4(aq)
Catalyzed by atmospheric dust

The progressively darker red areas on the map indicate the lowest pH levels and areas most prone to problems from acid rain.

Acid Rain
Smoke stacks pollute SO2
into the atmosphere. Thiscombines with water to formacid rain.
