Acid rain - Wikipedia
Acid rain - Wikipedia

Acid, rain is a rain or any other form of precipitation that is unusually acidic, meaning that it has 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 dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to ,produce, acids.
