Acid Rain can be defined as a special kind of highly acidic rainfall which contains much higher levels of hydrogen ions in the water.
Rainwater is anyway acidic, having a pH range of about 5.5 – 6. When the pH level of rains falls further, it is called Acid Rain.
Acid rain is caused by irresponsible combustion of fossil fuels, atmospheric pollutions through emission of nitrogen oxides (NO) and Sulphur dioxide (SO2).
Acid rains causes environmental depletion and material damage being high in sulphuric acid and nitric acid. It hugely damage plants, aquatic life, buildings, metal surfaces and more.
Acid rain can be in the form of normal rain, snowfall, fog, smog, hail or dew which are highly polluted with acids.
Acid rains mostly are a direct result of excessive air pollution, fossil fuel burns, smoke and industrial emissions. We must be careful to not cause air pollution if we want to avoid the dangers of acid rain.
