Here I discussed a topic of Chemistry by which you can understand my level of teaching and potential.

Acid Rain:-
Definition:-
As the name suggests, can be said as the precipitation of acid in the form of rain in the simplest manner. "When atmospheric pollutants like oxides of nitrogen and sulphur react with rainwater and come down with the rain, then this results in Acid Rain."

PH of acid Rain:-
Acid rain PH lies between 4.2 and 4.4
Normal rain has a pH of about 5.6.
Causes of Acid Rain:-
It causes respiratory issues in animals and humans.
When acid rain falls down and flows into the rivers and ponds it affects the aquatic ecosystem. It alters the chemical composition of the water, to a form which is actually harmful to the aquatic ecosystem to survive and causes water pollution.
Acid rain also causes the corrosion of water pipes, which further results in leaching of heavy metals such as iron, lead and copper into drinking water.
It damages the buildings and monuments made up of stones and metals.Sulphur dioxide and nitrogen dioxide undergo oxidation, and then they react with water resulting in the formation of sulphuric acid and nitric acid, respectively. The following reaction will clarify the acid formation reaction:

2SO2 (g) + O2 (g) + 2H2O (l) ? 2H2SO4 (aq)
4NO2 (g) + O2 (g) + 2H2O (l) ? 4HNO3 (aq)

Effects of Acid Rain
Acid rain is very harmful to agriculture, plants, and animals. It washes away all nutrients which are required for the growth and survival of plants. Acid rain affects agriculture by the way it alters the composition of the causes respiratory issues in animals and humans.

Real-Life Examples:-
Taj Mahal, one of the 7 wonders of the world, is largely affected by acid rain. The city of Agra has many industries which emit the oxides of sulphur and nitrogen in the atmosphere. People continue to use low-quality coal and firewood as a domestic fuel, adding to this problem. Acid rain has the following reaction with the marble (calcium carbonate):
CaCO3(s) + H2SO4(l) ? CaSO4(s) + H2O(l) + CO2(g)

Prevention of Acid Rain:-
The only precaution that we can take against acid rain is having a check at the emission of oxides of nitrogen and sulphur.
Acid rain is harmful to animals, plants and the monuments.
Being responsible citizens, one should be aware of the harmful effects they cause and of the industries which give out nitrogen and sulphur compound wastes unethically.
