The major sources for acid rain in atmosphere is

The phrase acid rain was first used in 1852 by Scottish chemist Robert Angus Smith during his investigation of rainwater Air and Rain: The Beginnings of a Chemical Climatology (1872). It was not until the late 1960s and early 1970s, however, that acid rain was recognized as a regional environmental issue affecting large areas of western

The extremely acidic rainfall that occurs due to environmental pollution is termed as acid rain. The main elements that influence acid rain are nitric acids and sulfur acids. When atmospheric pollution exceeds its limit, it causes acid rain spoiling the environment to a large extent. Various reasons contribute to acid rain. Some of these are natural causing processes, whereas some others are human activities that cause acid rain. Burning of fossil fuels, industrial activities, automobiles, etc. are the major human activities that cause acid rain. In simple terms, the increase in the acidity of water droplets makes the acid rain to happen. The pH level of the water droplets helps to determine the acidity of rain waterer. Normal water droplets of rain have a pH level of 5.3 to 6.0 which is weakly acidic. When the pH level of water droplets goes down below the normal pH level, it becomes more acidic and causes acid rain. In this article, we will try to understand little more about acid rain. Here, we will discuss the major causes of acid rain so that is a major environmental issue and leads to harmful effects. Also check – How is Acid Rain Caused? There are various sources of acid rain, some are human causing sources and some others are natural sources. However, out of these human causing sources contributes a ...

Acid Rain “Acid rain” became a household term in the 1980s when unchecked emissions from industry and motor vehicles were blamed for causing environmental deterioration. Scientific evidence has linked acid rain to decreased fish and wildlife populations, degraded lakes and streams, and human health hazards. Although the term has since faded from public consciousness, acid rain is a complex and global problem that still exists today. What is Acid Rain? First identified in 1872 in Sweden and studied in the U.S. beginning in the 1950s, acid rain is precipitation in the form of rain, snow, hail, dew, or fog that transports sulfur and nitrogen compounds from the high atmosphere to the ground. Sulfur dioxide (SO 2) and nitrogen oxides (NO, NO 2) are bi-products from burning fuels in electric utilities and from other industrial and natural sources. These chemicals react with water, oxygen, carbon dioxide, and sunlight in the atmosphere to form sulfuric and nitric acids. The acids reach the ground and change the chemistry within the environment. The acidity of any solution is determined on the pH scale of 0 to 14. A pH level of 0 to 7 is considered acidic; 7 is neural; and a level above 7 is alkaline. As the pH number decreases, acidity increases. Unopened bottled distilled water has a pH of 7, so it is neutral. In comparison, household ammonia is an alkaline with a pH of 11.5. Milk is slightly acidic with a 6.5 pH, and soft drinks, which contain phosphoric acid, have a 3.1 pH. Al...

Natural Sources - Lighting Bolts A natural source of nitrogen oxides occurs from a lightning stroke. The very high temperature in the vicinity of a lightning bolt causes the gases oxygen and nitrogen in the air to react to form nitric oxide. \[\ce\). Human Sources of Nitrogen Oxides At normal temperatures the oxygen and nitrogen gases do not react together. In the presence of very high temperatures nitrogen and oxygen do react together to form nitric oxide. These conditions are found in the combustion of coal and oil at electric power plants, and also during the combustion of gasoline in automobiles. Both of these sources contribute about equally to the formation of nitrogen oxides. In areas of high automobile traffic, such as in large cities, the amount of nitrogen oxides emitted into the atmosphere can be quite significant. In the Los Angeles area, the main source of acid rain is from automobiles. In certain national parks such as Yosemite and Sequoia, automobile traffic is banned to limit the amount of air pollution damage to the trees and plants. This also has the effect of reducing the visual smog in the air. Outside Links • Clyde, Dale D. " Dynamite Demo? ." J. Chem. Educ. 1995 72 1130. • Driscoll, Jerry A.

Acid rain, or acid deposition, is a broad term that includes any form of precipitation that contains acidic components, such as sulfuric acid or nitric acid. The precipitation is not necessarily wet or liquid; the definition includes dust, gases, rain, snow, fog and hail. The type of acid rain that contains water is called wet deposition. Acid rain formed with dust or gases is called dry deposition. The precipitation is not necessarily wet or liquid; the definition includes dust, gasses, rain, snow, fog and hail. The type of acid rain that contains water is called wet deposition. Acid rain formed with dust or gasses is called dry deposition. Causes of acid rain The term acid rain was coined in 1852 by Scottish chemist Robert Angus Smith, according to the Royal Society of Chemistry, which calls him the "father of acid rain." Smith decided on the term while examining rainwater Though manmade pollutants are currently affecting most acidic precipitation, natural disasters can be a factor as well. For example, volcanoes can cause acid rain by blasting pollutants into the air. These pollutants can be carried around the world in jet streams and turned into acid rain far from the volcano. After an asteroid supposedly wiped out the dinosaurs 65.5 million years ago, sulfur trioxide was blasted into the air. When it hit the air, it turned into sulfuric acid, generating a downpour of acid rain. Even before that, over 4 billion years ago, it is suspected that the air may have had 10,00...
