Why the flow of acid rain

Why the flow of acid rain into a river make the survival of aquatic life in a river difficult ?

  1. When pH value of rainwater is less than 5.6, it is called acid rain.
  2. When acid rain flows into the rivers, it lowers the pH of the river water.
  3. Living organisms can survive only in a narrow range of pH change.
  4. 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.
