Download file to see previous pages Acid rain is the "atmospheric deposition of acidified rain, snow, sleet, hail, acidifying gases and particles, as well as acidified fog and cloud water".It also refers to precipitation that is much more acidic than natural, unpolluted rain."The pH scale is used to measure the acidity or alkalinity of an aqueous solution and is determined by the hydrogen ion (H+) content" ("Measuring Acid Rain"). This scale ranges from 0 to 14, moving from strongly acid to strongly alkaline, respectively, with the point 7 representing neutral."The pH scale is logarithmic rather than linear". Hence, there is a tenfold increase in acidity with each pH point. Natural rain is mildly acidic because of the presence of carbon dioxide present in atmospheric moisture, which react together to form weak carbonic acid (H2CO3):H2CO3 is a weak acid and so it partially dissociates to release H+ (aq), resulting in the reduction of pH of the system. This partial ionization occurs in equilibrium, since carbonic acid only ionizes 1.7% ("Sources of Acid Rain"):The two dominant acids found in acid rain are sulfuric acid (H2SO4) and nitric acid (HNO3). These acids are created from the primary pollutants sulfur dioxide SO2 and nitrogen oxides such as NO2. These pollutants are usually carried over long distances from their primary source, where they finally result in acid rain. The chemistry of both these pollutants from this source to the creation of acid rain is shown below:Sulfur dioxide is mainly released into the atmosphere through combustion of fossil fuels. The world over, sulfur dioxide is also released by volcanoes and also by the oxidation of sulfur gases released by the decomposition of plants. This natural sulfur dioxide is released very high into the atmosphere, and hence the concentration of the gas is very minimal in unpolluted air. But the sulfur dioxide produced from the combustion of fossil fuels, for example in electric power plants and mined coal containing 1 to 5% sulfur, is released into the ground level air. The concentration of sulfur dioxide in the ground level air is, thus, quite high in certain areas, particularly in the northern hemisphere. This contributes to acid rain over large areas.

2. Nitrogen monoxide is produced as a byproduct of the burning of gasoline in car engines using air as the source of oxygen. The nitrogen present in air, when exposed to high temperatures inside car engines, is converted into the pollutant nitrogen monoxide (NO). A series of secondary reactions in the presence of sunlight produces nitrogen dioxide oxide and ground level ozone, which further precipitate acid rain reactions.

The gaseous NO3 then combines with any reactive hydrogen donor (X) in the atmosphere, producing aqueous nitric acid (HNO3): ...Download file to see next pagesRead More

A harmful impact of acid rain
...Acid RainAcid rain is a worldwide environmental issue that has seriously destroyed forest ecosystems” (Liu et al). When rain waterconsists of excessive acid content, we call it as acid rain. The development of industries, power plants and the increased use of automobiles have polluted the atmosphere immensely and as a result of that the normal structure of the atmosphere has been changed a lot. Nitrogen compounds and Sulfur oxides are some of the major gases which are coming out from industrial units, vehicles and power plants. These gases have the ability to combine with hydrogen present in...

The Realities of Acid Rain
... School 11/xx The Realities of Acid Rain Acid precipitation can take many forms including rainfall, snow, fogand particulate vapor collections of even more acidic water. This type of material can also be deposited in dry forms as dust-like particles which settle and coat objects as well as permeating the breathable atmosphere. The more acidic the compound the more likely that deposits will result in damage to property and conditions dangerous for organic life forms. Natural rainfall has a pH of 7, but the further pH levels drop below that number the more potentially harmful it will be for the environment (Eubanks, p.240). The pH level present is directly associated with the presence of sulfate oxides (SOx), nitrate oxides (NOx... ), and the...

Acid Rain
...HERE YOUR HERE YOUR HERE HERE Acid Rain: Definition, Impact and Potential Solutions Acid rain appears to be one of the most invasive problems facing contemporary society today. Acid rain occurs when, through a variety of industrial pollutants or natural phenomenon, the pH level of rainwater is changed from that of a basic property to one in which measurable changes in acidity are identified. Acid rain creates a wide variety of problems in the United States and abroad, however there are solutions to combat this growing international, ecological problem. This paper identifies the many...

...in their 1978 article indicate that coal supplies seventy percent of China’s energy needs, with over half of it being used in power plants for power generation and that China’s rainfall composition reflects her reliance on coal combustion to generate electricity as well as heating and cooking at homes. Generally, the available coal has high sulphur content and normally, they burn it in small stoves or furnaces devoid of pollution controls. In addition, with numerous sources that are low to the ground, pollution is kept near its origin. In 1978 for instance, in Guiyang City in China, compared to New York City’s levels, sulphate concentrations were approximately six times higher. Acid...

Acid Rain in Hamilton Ontario
...s School Topic: Acid Rain in Hamilton Ontario Synopsis The paper aims at studying the issue of acid rain by conducting an in-depth analysis of the environmental hazards attached with the problem. For this reason, Hamilton Ontario can be taken as a reference as this locale has been adversely affected by acid rain. Acid rain is a result of the various emissions in the atmosphere rich in nitrogen and sulphur, which are produced as a result of industrialization. Winds blowing from the US transmit cloud to Ontorio where acid rains are produced, and fuel emissions along with...

The Acid Rain
... Acid Rain: Causes and effects on the environment The human race has been progressing significantly since the day of its existence. This progress has helped the human race to improve the quality of life as well as create several more opportunities for further progress. But with every step we take towards a better life, either the human race or the world had to pay a price. With the development of factories, with the development of automobiles, the refrigeration systems have been emitting certain substances in the environment, causing enough damage to prove costly both for the planet earth and its resident. Looking back in the history, the rate of emission of these harmful substances has increased to a very dangerous level leading... to a...

Acid rain
...and Rain: The Beginning of a Chemical Climatology (1872) (Myers 267). Acid rains containing solutes of sulfuric and nitric acids cause serious damage to nature, because soil, water, vegetation, animals, and people become their victims. Gases that are released by burning of fossil fuels, among others, are composed from dioxins of sulfur and nitrogen. Depending on the composition of a certain fuel there may be more or less of these dioxins. Fuel oil and sour coal provide the most saturated sulfur dioxide emissions. Tons of sulfur dioxide emitted into the atmosphere resulting from chemical reactions turn into weak acid solution. In the...

Homework: Acid Rain Article
...Acid Rain Article There has been an increase in the percentage of CO2 in the atmosphere thanks to industrial activities and many other human activities that lead to emission of CO2 into the atmosphere. When it rains there is occurrence of acidic rain which is cause by the formation of carbonic acid. There has been an increasing trend from the year 1700 to the year 2007 and further increases are expected in the year 2007. According to Fig 1, the rate at which the PH of rainwater is decreasing is directly proportional to the increase in the volume of CO2 in the atmosphere. In fact is can be noticed that the rate at which the content of CO2...

...ACID RAIN Acid Rain Acid rain is defined by Kumar as a term used to de "Any precipitation which has a value less than 5.6,the PH of uncontaminated water".1 In most cases, Kumar notes that acid rain falls under a PH of between 5.6 and 3.5.2 It is important to note that evidence of acidic precipitation appears after a few days and long distances from the origin. Acid rain can be prevented through a number of ways in future. According to Casper, acid rain can be prevented in future is by switching to sources of energy that...
