Acid Rain and Deposition
¥Sulfur dioxide (SO2) and oxides of nitrogen (NOx) within clouds
(including fog) form acidic particles when they react
with water:
SO2
+ H2O Þ H2SO4 (sulfuric acid) NOx
+ H2O Þ HNO3 (nitric acid) ¥Acid Rain is worse downstream of the point sources of pollution
¥Acid Rain affects Trees, Lakes, Structures
¥Acid Deposition is a world-wide problem
