Question

Quizplus · Accepted Answer

Acid rain contains sulfur dioxide and nitrogen oxide, which can react with water to form sulfuric acid and nitric acid. These acids can increase the concentration of aluminum ions (Al3+) in the soil, which can leach into the groundwater and become toxic to plant growth. Therefore, choice B (Al3+) is the correct answer.
