  1. Corrosion of Acid Rain Juliana Lamond Grade 9

  2. The Problem • How does acid rain affect different materials? • I wanted to see how different materials would corrode over time • Would wonders of the world always be there to enjoy, how would acid rain affect them?

  3. Acid Rain • Pollutants go in air (sulfur dioxides, nitrogen oxides) • React with water molecules • Convert to acids • Acid deposition- wet deposition • Lack of plant growth, animals, bacteria • Freshwater • Buildings • Takes years to show the effect

  4. Hypothesis • If rocks, plants, sticks, and metals are soaked in acids similar to acid rain, then metal will corrode the most.

  5. Materials • Gloves • Eye goggles • 25 ml Sulfric acid • 25 ml Nitric acid • 25 ml Tap water • 2 plants • 4 beakers • Stick • Rock • Nail • Screw • Scale

  6. Procedure • Acidic solution was poured into various cups (the control) • 25 ml each of sulfric, nitric, and water • One plant was watered with solution, one with tap water • Different materials were weighed and placed in cups • After 24 hours, different materials were removed

  7. Graphs Nail Screw Grams Grams Number of Hours Soaked Number of Hours Soaked

  8. Conclusion • If rocks, plants, sticks, and metals are soaked in acids similar to acid rain, then metal will corrode the most. • Nail- lost .94 grams • Screw- lost 3.24 grams • The rock and stick did not corrode • Was supported, metals corroded the most • More trials • The plant watered with the acidic solution turned brown and died, and the plant watered with tap water stayed healthy
