Why the flow of acid rain into a river make the survival of aquatic life in a river difficult ?
- When pH value of rainwater is less than 5.6, it is called acid rain.
- When acid rain flows into the rivers, it lowers the pH of the river water.
- Living organisms can survive only in a narrow range of pH change.
- So flow of acid rain water into rivers is dangerous to the survival of aquatic life. These acids have free ions that conduct electric current.
