Why the flow of acid rainwater into a river make the survival of aquatic life in the river difficult?
The aquatic life survives in an optimum pH value. It is difficult for the aquatic life to maintain their metabolism in a pH value greater or less than the optimum pH value. When acid rainwater flows into a river it makes the river water acidic and disturbs the pH from its optimum value due to which the survival of aquatic life in the river becomes difficult.
