Acid rain is a form of precipitation usually acidic in nature. That means it contain low pH value. [ liquid with pH less than 7 are acidic . pH grater than 7 are alkaline ]. So the unpolluted rain has acidic pH. ( low pH ). Acid rain is caused by the emission of sulfur dioxide and nitrogen oxide. These two oxides react with water molecules in the atmosphere to produce acids. [ Sulfuric acid & Nitric acid ].
CAUSES:
Acid rain can damage the environment . Human health and property. Acid rain can causes paint to peel, corrosion of steel ( iron , copper ) structure. Erosion of stone statues ( limestone & marble ).
- In the presence of water sulfur trioxide is converted to sulfuric acid.
- Nitrogen dioxide react with OH to form nitric acid.
