what acid rain is
What is acid rain
If the pH of rainwater falls below 5.6, it is called acid rain. the atmosphere on the Earth’s surface Acid rain reveals how acid is deposited H plus ions are formed by the chemical reaction of rainwater with carbon dioxide in the atmosphere. In the presence of normal rainwater, the pH is 5.6.
Acidic nitrogen and sulfur oxides travel through the air along with solid particles in the atmosphere. Finally, dry deposits settle on the ground or as wet deposits in water, fog, and snow.
Carbon dioxide is the result of various human activities that release sulfur and nitrogen oxides into the atmosphere. Fossil fuels (sulfur, nitrogenous substances) such as coal and petrol, in power plants, Sulfur dioxide, and nitrogen oxides when burning petrol and diesel in motor engines when burning in furnaces Are formed.
After SO2 and NO2 are oxidized and reacted with water, they act as major constituents of Carbon dioxide. This is because polluted air usually contains particulate matter, which catalyzes the oxidation process. Does. Ammonium salts also form and appear in the form of atmospheric mist.
Ammonium salts in particles or raindrops in the form of oxide aerosols form wet deposits. SO2 is directly absorbed on solid, liquid, and soil surfaces and deposited as a dry deposit.
Why acid rain is harmful to plants
Acid rain is harmful to agriculture and plants. This is because it dissolves the nutrients needed for their growth and Removes them from them. Causes respiratory illnesses in humans and animals. Plants in the aquatic ecosystem when acid rain seeps into groundwater and flows into rivers and lakes. Disrupts animal life.
It dehydrates water transport pipes and adds heavy metals such as iron, lead, and copper to drinking water. Carbon dioxide can damage structures, buildings, and structures built of stone or metal. The Taj Mahal in India is acidic and Was exposed to rain.
