Acid Rain

Since most parts of the world have been industrialized, the pollution effect has plagued the country. Acid rain is one of the biggest causes of industrial pollution of this form. I will explain the adverse effect on the environment due to acid rain and the work to stop it through the report. Acid rain occurs when coal is used for power production, base metal smelting and automobile fuel burning.

Acid rain means what it means - rain is acidic. "Acid rain" is defined as rainwater with a pH less than 6. Due to dissolved gases in the rain, the rain becomes acidic. Approximately 70% of acid rain is formed by dissolved sulfur dioxide (SO 2) forming sulfuric acid. The remaining 30% comes from various nitrogen oxides (mainly NO 2 and NO 3 which have already adopted Mane Nox). A small amount of hydrochloric acid also constitutes hydrochloric acid. The expression is as follows.

Acid rain is a term composed of acid rain, snow, fog and particles. It is caused by sulfur dioxide and nitrogen oxides released from power plants' automobiles and other sources such as gas and oil. (EPA acid rain) Acid rain affects trees, earth, farms and surface water. As soon as the acid in the rain comes into contact with the object it starts chemical reaction. The pH value is a numerical value from 0 to 14 and measures the acidity of the substance. 0 is pure acid, 5 is the most neutral point, and 14 is the highest alkalinity. (Encarta Acid Rain, page 2)

Acid rain is a broad term that is widely used to explain some forms of acid rain. Wet deposition means that a large amount of sulfuric acid and nitric acid are present in rain, snow, fog or mist. As sulfur dioxide and nitrogen oxides are released into the atmosphere they dissolve in the water and fall with the precipitation. Dry deposition occurs when dust and smoke containing large amounts of sulfur dioxide and nitrogen oxides adhere to the ground, buildings, cars, plants. These gases are converted to acids when in contact with water. Acidity of acid rain may be different. The pH of pure water is 7, the pH of ordinary rain water is about 5.6. The rainfall in the United States in 2000 is only 4.3.

First, as its name suggests, acid rain is acid rain, pH is less than 5. PH is based on the concentration of hydrogen ion. Acid rain is caused by the release of sulfur dioxide and nitrogen oxides. These major pollutants are generated from factories, power plants, automobile emissions, chemical fertilizers, etc. Acid rain may damage human beings, animals, plants, aquatic organisms, soils, forests and other man-made objects. This list is always present. Most people do not think that acid rain is a big problem, but it is not so. Legislation to manage this problem has been enacted, but it is not useful for the United States to be what it should be. In this report I will explain the past controversy on acid rain and talk a little about the current situation.
