Acid rain is a term that refers to a mixture of wet and dry deposited material that contains higher amounts of sulfuric and nitric acids. Acid rain can be caused by natural phenomenon such as the ash from a volcanic eruption or decaying vegetation. Acid rain can also be human made from the combustion of fossil fuels that releases sulfur dioxide and nitrogen oxide. Acid rain transpires once these gases react within the atmosphere with oxygen, water, and other chemicals to create different acidic compounds. The effect of this reaction is a solution of sulfuric acid and nitric acid.
The term "Acid Rain" is a broad term that is used to emphasize on the fact that the rain has become acidic using certain pollutants, which may appear in different forms. For example, the dry deposition is when gases and dust particles become acidic, being able to affect a person 's health by inhaling it. On the other side, wet deposition is when it rains, polluting the trees and lakes. Acid rain is a result of two different sources; first is natural sources, such as decaying vegetation and volcanoes, and man-made sources, which basically consists of the formation of sulfur dioxide (SO2) and nitrogen oxides (NOx). Acid rain causes lake pollution and acidification, which would later also lead to the damage of trees and many different forest soils.
Introduction Acid rain is one of the common pollutants that affect some of the country. Acid rain was recovered first by Robert Angus Smith in 1852 in an article called ‘On the air and rain of Manchester’. Acid rain is more acidic due to presents of SO2, CO2 and NOx, when the pH is greater than 5.5, the atmosphere is alkaline. In contrast when pH is below 5.5, the atmosphere is become acidic and tend to fall an acid rain. Acid deposition is a process of air pollutants that can be deposited from the atmosphere to the earth into wet and dry form.
Even snow at time can be acid, also some gasses and particles that are not dissolved well in water with low pH can be more acidic than acid rain. So acid rain is formed when sulphur dioxide and nitrous acid raise very high into the atmosphere and mix with oxygen and water and many other chemicals to form acid rain. Because sulfur dioxide and nitrous oxides dissolve easily in water and carried by the wind, as it travels with the wind it can become part of rain, snow, fog, etc…
2.3 Effects of Acid Rain on the Environment and Human Society. Acid deposition is a serious regional problem occurring near and in many areas downwind from coal burning power plants, smelters, factories, and large urban areas according to Miller (1998). SO2 is emitted primarily by stationary sources such as power plants that burn fossil fuels whereas NOx are emitted by both stationary and mobile sources such as automobiles. How serious vegetation and aquatic life in nearby lakes are affected by receiving acid deposition depends on the alkalinity or acidity of its soils. In some areas, soils contain enough calcium ions (Ca2+) and magnesium ions (Mg+2) that are attached to the negatively charged minerals in the soil to neutralise or buffer the acid deposition.
Introduction: Rain is one of the most essential ingredients for the survival of human and animal life on Earth. Although rain is naturally acidic, it is being increasingly acidified by the presence of pollutants in the environment. The term used to describe this problem is “acid rain”  Burning of fossil fuels for industrial and transport sector have led to increase in concentrations of gaseous and particulate pollutants in the atmosphere leading to air pollution.  The oxides of Carbon, Sulfur and Nitrogen present in the air combine with the moisture in the air and form sulphuric acid, carbonic acid and nitric acid, respectively. When it rains or snow, these acids are brought to the earth in what is called acid rain.
There are many factors that effect soil pH such as precipitation, burning fossil fuel and parental materials in which the soils form from. Precipitation is one of the major factors that effect soil pH. Higher precipitation will cause the soil pH to decrease because Calcium and Magnesium gets leached away from the soil. Acid rain can also cause a significant change in the soil pH and this is caused by such things as gases produced when burning fossil fuel. When the acidifying elements remain in the gases produced, acid rain will occur causing the soil pH to decrease and become more acidic which leaches many of the soil nutrients.
Causes of acid rain its remediation and impacts on environment: Pure rain is naturally acidic with pH of 5.6 due to dissolved carbon dioxide in water vapor reacting to form carbonic acid( a very weak acid) The environmental pollution called acid rain is any rain with pH less than 5.6. Analysis of acid rain indicates that especially sulfur oxides and nitrogen oxides are mostly responsible for the rain acidity Causes of Acid Rain. Acid rain is rain consisting of water droplets that are unusually acidic because of atmospheric pollution - most notably the excessive amounts of sulfur and nitrogen released by cars and industrial processes. Acid rain is also called acid deposition because this term includes other forms of acidic precipitation such as snow. Cause of acid rain Scientists have discovered that air pollution from burning of fossil fuels is the major cause of acid rain.
Introduction Acid rain is rain that is acidic, meaning that it possesses elevated levels of hydrogen ions (low pH). It can have harmful effects on plants, aquatic animals and infrastructure. Acid rain is caused by the emissions of sulfur dioxide and nitrogen oxide, that react with the water molecules in the atmosphere to produce acids. The chemicals in acid rain can cause paint to peel, corrosion of steel structures such as bridges, and erosion of stone statues. Acid Rain have always been a problem for many countries.
Acid rain can damage vegetation, corrode metals and building materials, weaken organic fiber and destroy aquatic organisms. Acid rain decreases the pH of water bodies. Certain toxic substances like aluminum, lead and mercury which are insoluble otherwise, become soluble and can be life threatening to fish and other organisms.
