Why is acid rain considered a chemical reaction?

Acid rain results from chemical processes that’s why it is a chemical reaction. The oxides of sulphur and that of nitrogen ( SO2, SO3 , NO2 etc ) released from burning of fossil fuels from power stations and automobile exhaust fumes move in atmosphere . read more

To understand the chemistry of acid rain. Acid–base reactions can have a strong environmental impact. For example, a dramatic increase in the acidity of rain and snow over the past 150 years is dissolving marble and limestone surfaces, accelerating the corrosion of metal objects, and decreasing the pH of natural waters. read more

Sources of Acid Rain Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain. read more
