Why is acid rain more harmful than normal rain?
Answer and explanation
Correct answer: Because its pH is lower
Acid rain forms when atmospheric pollutants such as sulfur oxides and nitrogen oxides react with water and produce acids. Consequently, its pH is lower than that of ordinary rain, so it can be more corrosive. It may damage limestone buildings, disturb soil chemistry, and harm aquatic organisms. Therefore option A is correct. Normal rain is not always exactly neutral, but the defining issue here is the greater acidity, not the absence of ions or alkalinity.
