Answer 1

When pH value of rainwater is less than 5.6 is called acid rain.

When it enters into river, leading to the increase in acidic medium.

Aquatic animals can survive in narrow change in pH.

Acidic medium in river is dangerous for aquatic animals.

Answer 2

The low pH of the water makes the survival of aquatic life in a river difficult.

• The acid rain contains many acids like sulfuric acid, nitric acid etc. This acid has a very low pH.
• When the water of the acid rain flows into the river it decreases the pH of the river water. Thus, the water of the river becomes highly acidic and makes the survival of aquatic life in such a river difficult.
