Question

Explain the formation of acid rain. ???​

Answer 1

Explanation:

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

Both sulfur dioxide and nitrogen dioxide areacidic oxides and react with water to form acids. Sulfur dioxide reacts with water toform sulfurous acid. Substances in the upper atmosphere then catalyse the reaction between sulfurous acid and oxygen to form sulfuric acid.

Answer 2

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are liberated into the air.

• These substances rises very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

• Nature depends on balance, and although some rain is naturally acidic, with a pH level of around 5.0, due to the human activities it made it more worse.
• Normal precipitation—such as rain, sleet, or snow—reacts with alkaline chemicals, or non-acidic materials, that can be found in soils, bedrock, lakes, air, and streams.
• These reactions taking place usually neutralize natural acids.
• However, if precipitation becomes too acidic, these materials may not be able to neutralize all the acids.
