The statement is true because pollution that leads to the formation of acid rain does not solely originate from factories located in cities. While industrial emissions do contribute to acid rain, other sources such as vehicle emissions, agricultural activities, and natural processes like volcanic eruptions can also release pollutants that contribute to the formation of acid rain. Therefore, it is incorrect to assume that only factories in cities are responsible for acid rain formation.

Acid rain significantly lowers the pH levels of water bodies, making them more acidic. When sulfur dioxide (SO₂) and nitrogen oxides (NOₓ) are released into the atmosphere from industrial processes, power plants, and vehicle emissions, they react with water vapor to form sulfuric acid (H₂SO₄) and nitric acid (HNO₃). These acidic compounds then precipitate as acid rain, which can fall directly into lakes, rivers, and streams or be carried by runoff from surrounding land.

A scrubber is a machine that uses water or a solution to purify the gases being released from factories, power plants, etc. Scrubbers are commonly used in industrial settings to remove pollutants and harmful substances from the exhaust gases before they are released into the atmosphere. By spraying water or a scrubbing solution onto the gases, the scrubber helps to capture and remove pollutants, such as sulfur dioxide and particulate matter, effectively reducing air pollution and minimizing the impact on the environment.

Acid rain is often heavier near coastlines because airborne sea salts, which are more prevalent in coastal areas, can interact with atmospheric pollutants such as sulfur dioxide (SO₂) and nitrogen oxides (NOₓ). These sea salts can enhance the conversion of these pollutants into sulfuric acid (H₂SO₄) and nitric acid (HNO₃), which then fall as acid rain. The presence of these salts accelerates the chemical reactions that form acidic compounds, leading to more concentrated and frequent acid rain events in coastal regions. Additionally, coastal areas can experience increased deposition of pollutants carried by wind from inland industrial areas, further contributing to heavier acid rain.

Reducing emissions of sulfur dioxide (SO₂) and nitrogen oxides (NOₓ) from power plants, vehicles, and industrial processes is crucial for mitigating the formation of acid rain. SO₂ and NOₓ are primary pollutants that, when released into the atmosphere, react with water vapor and other chemicals to form sulfuric acid (H₂SO₄) and nitric acid (HNO₃). These acids then fall to the ground as acid rain, causing significant environmental damage.

The statement "Texas has the least amount of acid rain" is false. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which are released from burning fossil fuels. Texas is one of the largest producers of these emissions in the United States due to its large industrial and energy sectors. Therefore, it is unlikely that Texas has the least amount of acid rain compared to other regions with lower emissions.

Acid is the correct answer because acids are substances that release hydrogen ions (H+) when dissolved in water. These hydrogen ions make the solution acidic and give it its characteristic properties such as sour taste, ability to react with metals, and ability to turn blue litmus paper red. Oil, limestone, and nitrogen do not produce hydrogen ions in water and therefore are not the correct answers.

Acid rain is found most often in the East coast of the United States. This is because the East coast has a higher population density, more industrial activity, and greater air pollution compared to other parts of the country. These factors contribute to the release of pollutants such as sulfur dioxide and nitrogen oxides, which react with water vapor in the atmosphere to form acid rain. The prevailing wind patterns also carry these pollutants from industrial regions towards the East coast, further exacerbating the issue.

The Gothenburg Protocol to the Convention on Long-range Transboundary Air Pollution (CLRTAP) is a critical international agreement aimed at reducing the emissions of pollutants that contribute to acid rain, ground-level ozone, and other forms of air pollution. Signed in 1999 and amended in 2012, the Protocol addresses the need for coordinated action among countries to mitigate the environmental and health impacts of air pollution that crosses national borders.

Acid rain’s impact on soil and plant growth is profound, causing essential nutrients to leach out and altering soil pH, structure, and microbial activity. These changes reduce soil fertility, harm plant health, and lower agricultural productivity. Mitigating these effects through soil amendments, emission reductions, and sustainable farming practices is essential for preserving soil health and ensuring the long-term viability of agriculture.
