Question

What is the range of pH of acid rain?

• A. More than 5.6
• B. Less than 5.6
• C. In between 5.6 to 6.6
• D. In between 6.0 to 6.6

Answer 1

The correct option is B Less than 5.6

Normal, clean rain has a pH value of between 5.0 and 5.5, which is slightly acidic. However, when rain combines with sulfur dioxide or nitrogen oxides—produced from power plants and automobiles—the rain becomes much more acidic. Typical acid rain has a pH value of 4.0.
