Acid rain is the term used to describe raindrops that have become acidic in nature. Everything from soil to water on earth has a natural pH balance that it needs to maintain. When this pH balance increases or decreases, it changes the properties of the raindrops or the soil. When it rains, the air in the atmosphere is cleaned naturally.The raindrops usually collect the dust and other types of dry suspended particles in the atmosphere when they fall. The dry deposition naturally found in the atmosphere is volcanic dust and pollen or other particulate matter. |

Today, due to air pollution, there are several other types of particles found in the atmosphere and some are of acidic nature. We find sulfuric acid and nitrous oxide which are a result of pollution caused by industries and vehicles that burn fuel.
When the raindrops collect such acidic substances, they also become acidic in nature, and thus causing acid rain. In general, acid rain can be described as a rain that is high in sulfuric and nitric acid. The pH balance of acid rain is lower than 4 on the pH scale. A normal pH balance of raindrops is measured at 5.6 on the pH scale. Acid rain is harmful to the environment. It causes severe damage to sea life and they are the ones that suffer the most. When acid rain falls in the sea, it contaminates the sea water and decreases the pH balance of sea water. It also dissolves several minerals in the sea and changes the chemical composition of the water. Sea life is delicate and several fish die as a result.
