Question

The acid rain can make the survival of aquatic animals difficult. How?

Answer 1

Acid rain, caused by the release of sulfur dioxide \[\ce{(SO2)}\] and nitrogen oxides \[\ce{(NO_x)}\] into the atmosphere, reduces the pH of precipitation. Acid rain increases water acidity, threatening aquatic life by altering the pH balance required for living. Acidity can injure fish, amphibians, and other aquatic creatures by disrupting their reproductive, eating, and respiratory functions.
