Acid Rain • Rainfall that has been mixed with elements and gases that have caused the moisture to become more acidic • Pure water has a pH of 7 • Generally rainfall has a pH of about 6 • Acid rain can have a pH of 5.0-5.5 and in some parts of the world it can have a pH of 4
What causes acid rain? 1. Primary emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) resulting from fossil fuel combustion 2. Sulfur in the air combines with oxygen to form sulfur dioxide (SO2) 3. Car exhaust causes nitrogen oxides in the air (NOx) 4. From (SO2) and (NOx) airborne sulfuric acid (H2SO4) and nitric acid (HNO3) can be formed and dissolved in water vapor
