Question
By acid rain the pH of the water body
- is reduced
- is increased
- remains the same
- none
Answer
reduced
Explanation
By acid rain, the pH of the water body is reduced. Acid rain is rainwater that has a pH of less than 5.6 due to the presence of sulfur dioxide and nitrogen oxides, which react with water in the atmosphere to form sulfuric acid and nitric acid. When this acidic rainwater enters lakes, rivers, and other water bodies, it can lower their pH and make them more acidic, which can harm aquatic plants and animals.
