What is Acid Rain ?

Acid Rain in PA “Normal rain” is naturally slightly acidic Acid Rain has pH ______ < 5.6 - Show how normal rain is slightly acidic (carbonic acid) - CO2 + H2O  H2CO3 - Nearby industries: - PA’s average rainfall has pH of _____ 4.3 PA is affected more than any other state by Acid Rain due to nearby industries

Answers Question # 9 on Packet Page 6 Acid Rain Formation Burning fossil fuels (coal, oil, gas) NOx and SOx gases are emitted NOx and SOx combine with water in the sky to form nitric and sulfuric acid NO2 + H2O à SO2 + H2O à HNO3 H2SO4 Answers Question # 9 on Packet Page 6

Answers Question #8 on Packet Page 6 Effects of Acid Rain Minerals “leached” from soil Ex. Mg, Ca, K Metals (Al) dissolved from soil by rainwater get into water system Al(OH)3 + H2SO4  Al2(SO4 )3(aq) + H2CO3 Answers Question #8 on Packet Page 6

Answers Question #8 on Packet Page 6 Effects of Acid Rain - High levels of Al cause fish to build up mucous and can cause suffocation. - Waters with low pH can kill eggs - Low pH kills many bacteria & algae Answers Question #8 on Packet Page 6

Answers Question #8 on Packet Page 6 Effects of Acid Rain Dissolves waxy coating on plants – Dissolves CaCO3 (marble, limestone, concrete) Reacts with some metals leaves them vulnerable to fungus & bacteria Answers Question #8 on Packet Page 6

Effects of Acid Rain Since 1998, Harvard University wraps some of the bronze and marble statues on its campus, such as this “Chinese Stele", with waterproof covers every winter, in order to protect them from erosion caused by acid rain (or, actually, acid snow)

Acid Rain: Interstate & International - In the past, factories had short funnels to let out smoke. - This caused local pollution. - Now, factories have taller smoke stacks. - This leads to interstate and international pollution. Answers Question #10 on Packet Page 7
