  2. WHAT IS ACID RAIN • SO2 , Nox • TRACES OF NH4, Cl • LOW pH

  3. SULPHUR fossil fuels power plants residential combustion volcanoes and marsh gases NITROGEN fossil fuels coal plants denitrification forest fires, lightning SOURCES OF ACID RAIN

  4. OTHER SOURCES • Hydrocarbons • ammonia • chlorine

  5. THE REACTIONS • OH + SO2 HSO3 • HSO3 + O2  HSO5 • HSO5 + NO  [HSO4 + NO2] • HSO4 + NO2  H2SO4 + HNO3
