Which of the following gaseous air pollutants is known to cause acid rain?
Sulfur dioxide
Carbon monoxide
Nitrogen oxide
Ozone
Sulfur dioxide is a major contributor to acid rain, as it reacts with atmospheric moisture to form sulfuric acid. Acid rain can have negative impacts on aquatic life, forests, and infrastructure.Acid rain is a form of precipitation that has a lower pH value than normal rainwater (pH of 5.6). The pH of acid rain is usually below 5.0 and can even be as low as 2.0. The primary cause of acid rain is the emission of and
from human activities, such as burning of fossil fuels (e.g., coal and oil) for energy production and transportation, and industrial processes.
