with a pH of 5.6. Humans or natural occurrences can cause acid rain. For example‚ when a volcano erupts‚ it releases sulfur dioxide as one of the main components‚ which can enter the water and cause it to become acidic. However‚ the primary source of acid rain is the acidic compounds released by atmosphere pollution. Industrial processes like factories and motors like cars release sulfur dioxide (SO2) and nitrogen oxide and dioxide (NO2 or NO3‚ commonly written as NOx)‚ which are both strong acids when

Acid Rains There are three gases which could cause acid rain‚ which are Sulphur Dioxide (sulphuric acid)‚ NOx (oxides of nitrogen which produce nitric acid) and also perhaps Carbon Dioxide (weak carbonic acid)‚ produces these acids because these gases dissolve in rain water/ precipitation and this forms a weak version of the acid‚ as the gases dissolve it lowers the pH of the rainwater. I think that there has been a increase in the production of acid rain‚ due to the fact that the country as a

What it is: • the deposition of acidic components in rain‚ snow‚ dew‚ or dry particles. • more accurate term is "acid precipitation." • defined as any type of precipitation with a pH that is unusually low The Causes: • occurs when sulfur dioxide and nitrogen oxides are emitted into the atmosphere‚ undergo chemical transformations and are absorbed by water droplets in clouds • then fall to earth as rain‚ snow‚ mist‚ dry dust‚ hail‚ or sleet. • Dissolved carbon dioxide dissociates to form weak

many sensitive forest soils. In addition‚ acid rain accelerates the decay of building materials and paints‚ including irreplaceable buildings‚ statues‚ and sculptures that are part of our nation’s cultural heritage. Prior to falling to the earth‚ sulfur dioxide (SO2) and nitrogen oxide (NOx) gases and their particulate matter derivatives—sulfates and nitrates—contribute to visibility degradation and harm public health. Acid rain causes acidification of lakes and streams and contributes to the damage

reacting with the water and forming a weak carbonic acid. The acidity in the precipitations (rain‚ snow‚ fog) come from gasses released into the atmosphere by industrial factories‚ the combustion of fossil fuels‚ and even volcanoes. These gasses‚ sulfur dioxide and various nitrogen oxides‚ chemically react with the water vapors and oxygen in the atmosphere forming acidic vapors that will eventually rain back down on people‚ cities‚ and the environment. Normal rain water is a little acidic because

pollutant that is released is sulphur dioxide and nitrogen oxides. This is because when coal and fuels obtained from crude oil are burned‚ sulpur and nitrogen is released into the atmosphere‚ which is eventually joint with the oxygen in the air to produce sulfur dioxide and nitrogen oxide. When these gases are emitted in sufficient quantities‚ it reacts with the water and oxygen in the atmosphere to produce sulfuric acid and nitric acid which will mix with rainwater in clouds and form acidic solutions which

sources‚ primarily emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) resulting from fossil fuel combustion. In the United States‚ roughly 2/3 of all SO2 and 1/4 of all NOx come from electric power generation that relies on burning fossil fuels‚ like coal. Acid rain occurs when these gases react in the atmosphere with water‚ oxygen‚ and other chemicals to form various acidic compounds. The result is a mild solution of sulfuric acid and nitric acid. When sulfur dioxide and nitrogen oxides are

The term "acid rain“ was coined in 1872 by Robert Angus Smith. During the last decade‚ acid rain has been a major concern because it contnues to contaminate large areas of our planet. Acid rain occurs in the areas of major industrial emissions of sulfur dioxide and oxides of nitrogen . What problems are caused by acid rain? Acid rain causes a range of problems. Acid rain: increases the acidity levels of rivers‚ lakes and seas. This can kill aquatc life. Acid rain increases the acidity levels of

acid rain is caused by human activities. The biggest human activity that produces acid rain is the burning of fossil fuels by coal burning power plants‚ factories‚ and automobiles (EPA). When industrial factories and power plants burn fossil fuels‚ sulfur dioxide (SO2) and nitrogen oxides (NO) are released into the atmosphere. These chemicals react with water and oxygen to form mild solutions of nitric acid (HNO3)‚ and sulfuric acid (H2SO4)‚ as shown below (EPA). Decomposing vegetation release carbon
