“When the pH of rain water drops below to 5.6 is called acid rain.” Or It can be defined as: “rainwater having pH less than 05”.
Acid rain is a type of environmental pollution that occurs when acidic substances, such as sulfur dioxide and nitrogen oxides, react with atmospheric moisture and fall to the ground in the form of rain, snow, or dry particles
Acid rain harms aquatic life and damages soil, forests, and plants, agricultural crops
