“Acid u” is a popular term referring to the deposition of wet (rain, snow, sleet, fog, cloud water, and dew) and dry (acidifying particles and gases) acidic components.Distilled water, once carbon dioxide is removed, has a neutral p H of 7.

Essay on Acid Rain: Definition, Causes, Adverse Effects and Control! Smith in 1872 from his studies of air in Manchester, England.
The widespread occurrence of acid rain was recognized only in 1980.
This can be responsible for as much as 20 to 60% of total acid deposition.
This occurs when particles and gases stick to the ground, plants or other surfaces.
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 1970s to reduce the release of sulphur dioxide into the atmosphere with positive results.Parts of India such as North East, Coastal regions of Kerela, Orissa, Bihar, and West Bengal have reported decline in fertility of soil due to reduced p H of soil (increased in acidity).Acid rain is the phenomenon of wet and dry acidic deposition.Acid rain is a rain or any other form of precipitation that is unusually acidic, i.e., elevated levels of hydrogen ions (low p H).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.The gases responsible for acid deposition are normally a by-product of electric power generation and the burning of coal.As such, it began entering the atmosphere in large amounts during the Industrial Revolution and was first discovered by a Scottish chemist, Robert Angus Smith, in 1852.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.Liquids with a p H less than 7 are acidic, and those with a p H greater than 7 are alkaline.“Clean” or unpolluted rain has an acidic p H, but usually no lower than 5.7, because carbon dioxide and water in the air react together to form carbonic acid, a weak acid.
