Acid Deposition Reactions (idk if they're right)

• Types of oxides of sulfur:

  • H2SO3 or H2SO4: SO2(g) + H2O(l) ->H2SO3(aq) and SO3(g) + H2O(l) -> H2SO4(aq)
  • SO2: S(s) + O2(g) -> SO2(g)
  • SO3: SO2(g) + 1/2O2(g) -> SO3(g)
  • made in presence of sunlight (oxidized)
• Formation equation of nitrogen monoxide:

  N2(g) + O2(g) -> 2NO2 (g)
• Oxidation of nitrogen monoxide to nitrogen dioxide occurs in the air:

  NO2 (g) + O2 (g) -> N2 (g) + NO2 (g)
• Nitrogen dioxide can react with water to form nitric acid and nitrous acid:

  NO2 (g) + H2O (l) -> HNO3 (aq) + HNO2 (aq)
• Nitrogen dioxide can also be oxidized to nitric acid:

  NO2 (g) + O2 (g) + 2H20 (l) -> 4HNO3 (aq)
