Question

Write balanced chemical equations for the formation of acid rain.

Answer 1

Hint: The color of the Taj Mahal has changed from white to yellow because of the oxide of sulfur and nitrogen dissolve in rainwater and form acid (known as acid rain), and when this acid rain falls on it, then the color changes from white to yellow.
It is the acid rain that is most dangerous for the monument. Indeed, the inadvertent emission of sulfur dioxide, due to road traffic, causes acid rain.

Complete step by step answer:
When sunlight strikes on the earth's surface it gets heated. As a result, at the surface water is heated and converted into vapor.
The water vapors evaporate from the sea river ponds and go up into the atmosphere. When it reaches the upper atmosphere due to the cold temperature the water becomes cool, and condenses into water molecules that snow, and makes clouds. When the water molecules become bigger by condensation, it falls into the surface of the earth again and returns into the sea river, pond, etc. This is a significant aspect of the weather change on earth. This is called rainfall. Due to this rainfall, all the dust particles of the air settle down to the earth's surface and the sky becomes clear.
Now, due to so many pollutions, sulfur dioxides, sulfur trioxide nitrogen dioxide, react with water and make the rainwater acidic and form acid rain. The reactions are shown below,
\[S{O_2} + 3{H_{2}}O \to {H_2}S{O_3}_ + 2{H_2}\]
\[S{O_3} + {H_{2}}O \to {H_{2}}S{O_4}\]
\[2N{O_2} + 2{H_2}O \to 2HN{O_{3}} + {H_2}\].

Note: A great way to reduce acid rain is to produce energy without using fossil fuels. Instead, people can use renewable energy sources, such as solar and wind power. Renewable energy sources help to reduce acid rain because they produce much less pollution.
