Fossil fuel combustion at electric power-generating plants accounts for about70% of the emissions. Coal, Oil, and all other fossil fuels naturally contain some sulfur. Volcanic eruptions are another more localized natural source of SO2 SO2 + OH. HSO3. HSO3. + O2 SO3 + HOO. SO3 + H2O H2SO4(g) H2SO4 + H2O H2SO4 (aq) The Fate of Atmospheric SO2: Acid Rain HSO3- = H+ and Ka = 1.7 x 10-2 = HSO3- H+ = HSO3- 2 H2SO3 1.0 x 10-7 HSO3- = 4.1 x 10-5 M So the ratio of HSO3- to H2SO3 is 410:1 (4.1 x 10-5 /1.0 x 10-7). Because HSO3- = H+ = 4.1 x 10-5 M 키워드 환경화학, troposphere, Chemistry
