FAQs on Acid Rain Video Lecture - Chemistry Class 11 - NEET

1. What is acid rain and how is it formed?
Ans. Acid rain is a type of rainfall that is highly acidic, with a pH level below 5.6. It is formed when emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) react with the atmosphere's moisture, resulting in sulfuric acid and nitric acid. These emissions mainly come from burning fossil fuels such as coal and oil in power plants, factories, and vehicles.
2. What are the main causes of acid rain?
Ans. The main causes of acid rain are the emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx). These gases are released into the atmosphere from various human activities, including burning fossil fuels, industrial processes, and transportation. When these gases react with moisture in the air, they form sulfuric acid and nitric acid, leading to the formation of acid rain.
3. What are the environmental effects of acid rain?
Ans. Acid rain has several detrimental effects on the environment. It can acidify lakes, rivers, and streams, making the water too acidic for aquatic life to survive. It also damages forests by leaching essential nutrients from the soil and weakening trees, making them more susceptible to diseases and pests. Additionally, acid rain can corrode buildings, monuments, and statues made of limestone or marble, causing irreversible damage.
4. How does acid rain impact human health?
Ans. Acid rain does not directly impact human health. However, the pollutants that contribute to acid rain, such as sulfur dioxide and nitrogen oxides, can have adverse effects on human health when inhaled. These pollutants can irritate the respiratory system, exacerbate asthma symptoms, and contribute to the formation of respiratory illnesses. They can also react with other pollutants in the atmosphere to form fine particulate matter, which has been linked to cardiovascular and respiratory problems.
5. How can acid rain be reduced or prevented?
Ans. Acid rain can be reduced or prevented through various measures. One effective approach is to reduce emissions of sulfur dioxide and nitrogen oxides by implementing stricter regulations on industrial processes, power plants, and vehicles. This can be achieved through the use of cleaner technologies, such as scrubbers in smokestacks and catalytic converters in vehicles. Additionally, promoting renewable energy sources and energy efficiency can help decrease the reliance on fossil fuels, further reducing the emissions that contribute to acid rain. International cooperation and agreements also play a crucial role in addressing the issue of acid rain.
