Solution

Dear Student,
Acid rain is a rain that is unusually acidic due to the presence of acids such as sulphuric acid (H2SO4) and nitric acid (HNO3). Rain is acidified by oxides of sulphur and nitrogen. Acid rain usually has a pH of 5.6. It is formed when pollutants such as oxides of sulphur and nitrogen (like sulphur dioxide, nitric oxide etc), contained in power plant smoke, factory smoke, react with the moisture in the atmosphere to form sulphuric acid and nitric acid.In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulphur dioxide into the air. These pollutants cause acid rain

It can have harmful effects on plants, aquatic animals, and infrastructure. Following are the harmful effects of acid rain

  • Dissolves nutrients essential for plant growth

  • Causes respiratory ailments in humans

  • Affects aquatic ecosystem

  • Corrodes water pipes resulting in leaching of heavy metals in drinking water

  • Damage buildings made up of stone and metal
