Essay on Acid Rain: Definition, Causes, Adverse Effects and Control! Smith in from his studies of air in Manchester, England. The widespread occurrence of acid rain was recognized only in Acid rain is a rain or any other form of precipitation that is unusually acidic, i.
What we call acid rain is the oxides of sulphur and nitrogen originating from industrial operations and fossil fuel combustion, the major sources of acid forming gases combine with the water in the air. Acid forming gases are oxidized over several days by which time they travel several thousand kilometres.
In the atmosphere these gases are ultimately converted into sulphuric and nitric acids. This acidic mixture then falls as rain, sleet, mist or snow or as solid flakes. Hydrogen chloride emission forms hydrochloric acid. These acids cause acidic rain. Rain water is turned acidic when its pH falls below 5.
In fact clean or natural rain water has a pH of 5. Acid rain is the phenomenon of wet and dry acidic deposition. This can result from the deposition of acids produced in the raindrops see aqueous phase chemistry above or by the precipitation removing the acids either in clouds or below clouds.
Wet removal of both gases and aerosols are both of importance for wet deposition. Acid deposition also occurs via dry deposition in the absence of precipitation. This occurs when particles and gases stick to the ground, plants or other surfaces.
During the last few decades acid rain occurred within the downwind of areas of major industrial areas in Europe and America. Emissions of sulphur dioxide SO2 into sulphate or NO2 into nitrate particles and by combining with water vapour into mild sulphuric or nitric acids and return to earth as dew, drizzle, fog, sleet, snow, and rain is the mechanism of acid rain.
Acid rain is a rain or any other form of precipitation that is unusually toxic, 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 emissions of sulphur dioxide and nitrogen acids, which react with the water, smell molecules in the atmosphere to produce acids. Governments have made efforts since the s to reduce the release of sulphur dioxide into the atmosphere with positive results.
Nitrogen oxides can also be produced naturally by lightning strikes and sulphur dioxide is produced by volcanic eruptions. The chemicals in acid rain can cause paint to peel, corrosion of steel structures such as bridges, and erosion of stone statues.
Distilled water, once carbon dioxide is removed, has a neutral pH of 7. Liquids with a pH less than 7 are acidic, and those with a pH greater than 7 are alkaline.
However, unpolluted rain can also contain other chemicals which affect its pH.
A common example is nitric acid produced by electric discharge in the atmosphere such as lightning. Carbonic acid is formed by the reaction. Carbonic acid then can ionize in water forming low concentrations of hydronium and carbonate ions:Acid Rain Cause and Effect Essay Example. Acid rain refers to rain water that has a pH level below It has been identified as one of the major causes of environmental pollution in the world today.

Essay on Acid Rain: Definition, Causes, Adverse Effects and Control! The term ‘Acid Rain’ was first used by Robert A. Smith in from his studies of air in Manchester, England. The widespread occurrence of acid rain was recognized only in Acid- Rain do not effect just water environments and land but one of the serious side effects of acid rain on human is "respiratory" problems.
The dioxide and nitrogen oxide emission gives risk to respiratory problems such as dry coughs, asthma, headaches, eye, nose, and throat irritation.
