Acid Rain and Global Warming: Effects and Solutions

Explore the relationship between acid rain and global warming, their impact on the environment, and potential solutions. Understand the chemistry behind acid rain formation and its effects on pH levels in lakes, rivers, and oceans. Learn about the increasing ocean acidity due to rising CO2 levels and its long-term consequences. Also, gain insights into the role of fossil fuels, energy policy, and their impact on the global economy and job market.

  13. “Acid” Rain The pH of “clean” rain is slightly acidic ~5.6 (< 7 is acidic) due to the CO2 - carbonic acid, H2CO3 (aq) (Seltzer) CO2 (g) + H2O(l) H2CO3 (aq) H3O+(aq) + HCO3-(aq) Acids are also produced by the reaction of sulfur dioxide and sulfur trioxide with water, which adds to the acidity of rain. SO2 (g) + H2O(l) H2SO3 (aq) 2 SO2 (g) + O2 (g) 2 SO3 (g) SO3 (g) + H2O(l) H2SO4 (aq)

  14. Acid Rain - Tolerances CO2 (g) + H2O(l) H2CO3 (aq) H3O+(aq) + HCO3-(aq) SO3 (g) + H2O(l) H2SO4 (aq) Frogs are the most tolerant on the list. Clams & snails most sensitive.

  15. Acid Rain CO2 (g) + H2O(l) H2CO3 (aq) H3O+(aq) + HCO3-(aq) SO3 (g) + H2O(l) H2SO4 (aq) Effects on marble, limestone & (old) blackboard chalk, CaCO3?
