Question

which substance in acid rain makes it more acidic than natural rainwater?

a. oil

b. ph paper

c. sulfuric acid

d. coal

Explanation:

Natural rainwater is slightly acidic due to dissolved carbon dioxide. Acid rain is more acidic because of pollutants like sulfur dioxide and nitrogen oxides that react in the atmosphere to form acids, with sulfuric acid (from sulfur dioxide) being a key acidic substance. Oil, pH paper, and coal are not the substances that directly make rain more acidic. So the correct option is C.

Answer:

C. Sulfuric acid
