what is acid rain and what is its effect?

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 less than 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, and car exhaust, react with the moisture in the atmosphere to form sulphuric acid and nitric acid.

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

Acid rain is rainfall that has been acidified. Rain is acidified by oxides of sulphur and nitrogen. Acid rain usually has a pH of less than 5.6. It is formed when pollutants called oxides of sulphur and nitrogen, present in factory smoke, and car exhaust, react with the moisture in the atmosphere. On acid rain, the soil become infertile, water become acidic this cannot be used for drinking and other works, the building and monument get highly damaged. The environment becomes harmful due to presence of toxic gases for breathing. The life on planet becomes difficult to survive.

The first rain of the seasion is called ''Acid rain"". rain is acdified by oxide of sulphur and nitrogen. its pH = 5.6 [LESS THAN].

EFFECTS OF ACID RAIN ARE .................

1.> It effect the skin of living beings.

2.> it also damage the infrastructure like [TAJ-MAHAL].

3.> It creat problem at the time of breathing.

4.> it get impure the water ; by this drinking water is also ''acidic''.

When rain water is mixed with nitric acid or sulphuric acid its pH which is orignally 7 decreases to 5.5 or becomes less than 5.5 then it causes acid rain. Acid rain can affect-

  • The walls of monuments and building as the acids react with their walls spoiling them.
  • It can affect skin of human beings.
  • It can kill aquatic animals as it changes the pH of water.
