Acid rain harms plants, agriculture and trees. It also causes respiratory problems in humans. Acid rain damages buildings and structures made of metal and stone.
This environmental problem is called acid rain Precipitation that is dramatically more acidic because of human activities. and has significant consequences for all living organisms. To understand acid rain requires an understanding of acid–base reactions in aqueous solution.
Acid rain was discovered in the 19th century by Robert Angus Smith, a pharmacist from Manchester (England), who measured high levels of acidity in rain falling over industrial regions of England and contrasted them to the much lower levels he observed in less polluted areas near the coast.
