  • 2. Acid rain
    By Luiz Paulo CARNEIRO
    ChemicalEngineer, specializing in Environmental
  • 3. How Acid RainWorks
    Acid rain occurs mostly in the Northern Hemisphere
    Acid rain, also known as acid deposition, is caused by emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx)from power plants, cars and factories.
    SO2 / NOx + H2O-> H2SO4 / HNO3
  • 4. The pH of Acid Rain
    Express the acidity of acid rain using the pH scale.
    The scale defines a solution's acidity, neutrality or alkalinity based on its concentration of hydrogen ions. ( 0 – 14 pH)
    Acids – pH > 7,0
    Most life is comfortable at a near- neutral pH (7,0
  • 5. The pH of Acid Rain
    Acidrain - pH of 5.0 orless. Mostaciddeposition ranges from pH 4.3 to 5.0
  • 6. The Effects of Acid Rain
  • 7. The Effects of Acid Rain
    Ex: Oldbuildings, monumentstombstones, automotivepaint
  • 8. The Effects of Acid Rain
    Effects for our health
    Sulfate (SO4), nitrate (NO3) particulates of dry deposition can ­cause asthma, bronchitis and heart problems.
    The NOx in acid deposition also reacts with volatile organic compounds (VOCs) to form ground-level ozone (O3). Ozone, or smog, aggravates and weakens the respiratory system.
