Acid rain occurs when sulfur dioxide and nitrogen oxides are emitted into the atmosphere, undergo chemical transformations and are absorbed by water droplets in clouds. The droplets then fall to earth as rain, snow, or sleet. This can increase the acidity of the soil, and affect the chemical balance of lakes and streams. [1]. Acid rain is sometimes used more generally to include all forms of acid deposition - both wet deposition, where acidic gases and particles are removed by rain or other precipitation, and dry deposition removal of gases and particles to the Earth's surface in the absence of precipitation.[2]\n\nAcid rain is defined as any type of precipitation with a pH that is unusually low (Brimblecombe, 1996). Dissolved carbon dioxide dissociates to form weak carbonic acid giving a pH of approximately 5.6 at typical atmospheric concentrations of CO2 (Seinfeld and Pandis, 1998). Therefore a pH of <5.6 has sometimes been used as a definition of acid rain [3]. However, natural sources of acidity mean that in remote areas, rain has a pH which is between 4.5 and 5.6 with an average value of 5.0 and so rain with a pH <5 is a more appropriate definition [4].\n\nAcid rain accelerates weathering in carbonate rocks and accelerates building weathering. It also contributes to acidic rivers, streams, and damage to trees at high elevation. Efforts to combat this phenomenon are ongoing.\n\nContents [hide]\n1 History and trends \n2 Emissions of chemicals leading to acidification \n2.1 Natural emissions \n2.2 Human emissions \n2.3 Gas phase chemistry \n2.4 Chemistry in cloud droplets \n3 Aerosol formation \n4 Acid deposition \n4.1 Wet deposition \n4.2 Dry deposition \n5 Adverse effects \n5.1 Effects on lake ecology \n5.2 Effects of acid rain on soil chemistry \n5.3 Effects of acid rain on soil biology \n5.4 Other adverse effects \n6 Prevention methods \n6.1 Technical solutions \n6.2 International treaties \n6.3 Emissions trading \n7 References \n8 External links \n9 See also \n \n\n\n[edit]\nHistory and trends\nAcid rain was first reported in Manchester, England, which was an important city during the Industrial Revolution. In 1852, Robert Angus Smith found the relationship between acid rain and atmospheric pollution. The term "acid rain" was used for the first time by him in 1872 (Seinfeld and Pandis, 1998).\n\nThough acid rain was discovered in 1852, it wasn't until the late 1960s that scientists began widely observing and studying the phenomenon. Canadian Harold Harvey was among the first to research a "dead" lake. Public awareness of acid rain in the U.S increased in the 1990s after the New York Times promulgated reports from the Hubbard Brook Experimental Forest in New Hampshire of the myriad deleterious environmental effects demonstrated to result from it.\n\nEvidence for an increase in the levels of acid rain comes from analysing layers of glacial ice. These show a sudden decrease in pH from the start of the industrial revolution of 6 to 4.5 or 4. Other information has been gathered from studying organisms known as diatoms which inhabit ponds. Over the years these die and are deposited in layers of sediment on the bottoms of the ponds. Diatoms thrive in certain pHs, so the numbers of diatoms found in layers of increasing depth give an indication of the change in pH over the years.\n\nSince the industrial revolution, emissions of sulfur and nitrogen oxides to the atmosphere have increased. Industrial and energy-generating facilities that burn fossil fuels, primarily coal, are the principal sources of increased sulfur oxides. Occasional pH readings of well below 2.4 (the acidity of vinegar) have been reported in industrialized areas. These sources, plus the transportation sector, are the major originators of increased nitrogen oxides.\n\nThe problem of acid rain not only has increased with population and industrial growth, but has become more widespread.

I'm curious.... If it's due tomorrow, how long have you had to research it?  In any case, you are in luck!  This is the technological age and you can GOOGLE IT!\n\nBest Wishes,\n\nSue

These lessons worked well for me:\nTo illustrate acid rain- Take 2 small identical plants, water one with plain water and one with a vinegar/water solution. Give it a week or two and the 'acid treated' plant will show results.\nTo illustrate the importance of recycling and the concept of biodegradability: Take a big pot of dirt. Bury an apple core, a piece of aluminum foil or styrofoam and a bottle cap. After 30 days or so, (make a big deal out of marking the days off on a calendar) dig up each of the items and talk about why the apple core dissolved and \nthe other stuff did not. Talk about the concept of 'land fill' and how this stuff will NEVER go away.\nTo illustrate erosion, plant 2 or 3 small plants in a shallow dish.Take another dish and just put rocks and dirt in it.  Put both at an angle and pour water slowly over them. Discuss how the water erodes the soil because there are no plant roots to keep the soil in place- which is a result of deforestation.\nTake old newspapers, tear them into little pieces, soak them in water, mush them up in a blender, drain them through a sieve, lay the pulp out to dryin flat sheets and you have made recycled paper.

err..well if you mean as in..acid rain..\nin most areas in the US, rain is slightly acidic.\nIf the rain is unpolluted, then the acidity comes from a weak acid called Carbonic Acid which forms when carbon dioxide reacts with the water. Any extra acidity in rain is a result of pollutants. The two main chemical components are nitrogen oxides and sulfur oxides which react with water to form nitric acids and sulfuric acids. These pollutants come from cars, buses, all that kind of stuff. (:

Hi!  This has been my fav. site when it came to doing science projects so far.  http://www.stevespanglerscience.com/index.php\nRemember to call your local papers and have a write up done on it so you have a good turn out for the crowd.  Good luck!

It is then Acid Rain. Not Good.

acid rain!!!! \n\nit is widely believed that the acid rain is the result of wash out from the atmosphere, of the "acid rain gases", namely sulphurdioxide and nitrogen oxides. \n\nboth wet and dry deposits corrode metallic structures and deteriorate the quality of paint. \n\nthe deposition is particularly harmful to stone buildings, statues and monument.

It is actually a very strong acid which has a pH value of less than 2...I think it is 0 or 1. Sulphuric acid can cause acid rain which destroys our environment. To recover those destruction, it has an effect in the economy of the place or a country. Besides acid rain, acids react with metal which corrodes them or makes them rusty.. This might lead to more damage of pipes which eventually might burst if there is excess. To repair them also has an economical effect. These are the disadvantages....however, ont he bright side, sulphuric acid can be used to neutralize alkali. this is a way to save the environment and money. However, sulphuric acid can be expensive sometimes...(not sure)..
