Introduction Rain is naturally acidic due to the dissolution of carbon dioxide forming weak carbonic ac Acid rain refers to rain that has a higher hydrogen ion concentration than about 10 5 M Acid rain occurs due to the dissolution of acidic oxides in the atmosphere Sulfur dioxide is one such acidic oxide which is produced by natural means such as volcanoes and geothermal hot springs and Sulfur dioxide dissolves easily in water to form sulfuric ac Sulfuric acid is a major component of acid rain Acid rain can damage forests and crops change the acidity of soils and make lakes and streams acidic and unsuitable for fish Sulfur dioxide also contributes to the decay of building materials and paints including monuments and
立即联系/Live ChatAcid rain is often a problem in regions that are 100s even s of miles from the source of the sulfur dioxide Acid rain in Canada could come from sources in the US acid rain in Scandinavia came from industrialized areas in other parts of EuropeOct 28 32 Acid rain is a byproduct of burning coal and oil for energy the combustion process releases sulfur and nitrogen dioxide into the air which bond with water and oxygen molecules and then fall to the ground as sulfuric and nitric ac Acid rain eats away at building exteriors dissolves paint finishes and erodes monuments
立即联系/Live ChatAcid rain simply refers to rain or other precipitants that have uncommonly high acidity This is a result of SO2 in the air that dissolves in water creating sulfuric ac The source of this SO2 is largely power plants that burn fossil fuelsacid rain SO2 ie sulfur dioxide reacts with water to produce H2SO3 or sulfurous acid which then reacts with oxygen to form sulphuric acid H2SO4 and dissolves in rain to fall as acid rain
立即联系/Live ChatFeb 13 32 A recent Harvard report reflects on the success of the SO2 allowance trading program used to curb acid rain The authors note that cap and trade seems especially well When sulfur dioxide combines with water and air it forms sulfuric acid which is the main component of acid rain Acid rain can cause deforestation acidify waterways to the detriment of aquatic life corrode building materials and paints In Queensland there is less heavy industry than in Europe or North America where the potential for
立即联系/Live ChatPrimary Causes of Acid Rain Acid rain is formed by elevated levels of sulfur and nitric acids in the atmospheres that accumulate as a result of Nitrogen oxides NOx and Sulfur dioxides SO2 emissions Acid rain is a mix of atmospheric water molecules and dry depositions of Sulfur dioxides and Nitrogen oxides emitted from industries and vehiclAcid rain has existed since the first factories of the Industrial Revolution began spitting out toxic emissions An English scientist Robert Angus Smith coined the term acid rain in when he wrote of its corroding touch on buildings and deadly effect on plants But acid rain did not become a

立即联系/Live ChatThe Chemistry of Acid Rain Key Concepts Rain from an unpolluted atmosphere has a pH close to 60 slightly acidic This acidity is due to the reaction of water vapour and non metal oxides in the atmosphere such as carbon dioxide and nitrogen oxide forming dilute acids carbon dioxide reacts with water to form carbonic acid EMISSIONS Acid Rain Program SO2 Market Overview In the EPA began Phase II of the sulfur dioxide SO2 program Under Title IV of the Clean Air Act Amendments SO2 emissions must be reduced by 10 million tons from levels The program is a national program that currently affects all existing utility generators with an output
