Effects Of Acid Rain Sulfur Dioxide And Nitrogen
3,730 wordsWhat is acid rain? Acid rain is the term for pollution caused when sulfur and nitrogen dioxides combine with atmospheric moisture. The term 'acid rain' is slightly misleading, and would be more accurate if deemed 'enhanced acid rain', as rain occurs acidic naturally. Acidity is measured on what is know as the pH scale. Fourteen is the most basic, seven is the most neutral, and zero is the most acidic. Pure rain has a pH level of 7, which is exactly neutral. The acidity of rain is determined by t...

The corrosive nature of acid rain causes widespread damage to the environment. The problem begins with the production of sulfur dioxide and nitrogen oxides from the burning of fossil fuels, such as coal, natural gas, oil and other kinds of manufacturing. When these pollutants are in the air, they react with water and other chemicals, to form sulfuric...

Clean Air Act H 2 O
1,801 wordsAcid rain is exactly what it suggests- rain that is acidic. The definition of 'acid rain' is rain with a pH of below 5. 6. Rain becomes acidic because of gases that dissolve in the rain. Approximately 70 % of acid rain is a result of dissolved sulfur dioxide (SO 2) which forms Sulfuric Acid. The remaining 30 % or so comes from various Nitrogen Oxides (mostly NO 2 and NO 3 which has collectedly adopted the mane Nox). There is also a small percentage of hydrochloric acid that makes up hydrochloric...
