Acid Rain

What exactly causes acidic rain to form? Why is it possible for rain to be acidic?

Acidic rain forms from sulfur dioxide and nitrogen are released in to the air (as from coal power plants) and interact with water or oxygen.

This value is considered neutral—neither acidic or basic. Normal, clean rain has a pH value of between 5.0 and 5.5, which is slightly acidic. However, when rain combines with sulfur dioxide or nitrogen oxides—produced from power plants and automobiles—the rain becomes much more acidic.

The water molecules in rain react with pollutants in the air and becomes acidic in nature

One more thing to know is that rain is normally acidic, and the acid rain is when rain is too acidic (more than normal).

Mainly caused by chemicals like SO4^2- and NO3- coming from burning fossil fuels, such as coal.

It is possible for rain to be acidic because as it falls from the atmosphere, it collects impurities which change the pH of the rain water to be acidic or alkaline.

SO2 reacts with water vapor to form acidic rain. (SO2 comes from burning petroleum products, coal, etc.)
SO2(g) + H2O(l) → H2SO3(aq)

Is acid rain formed from SO2 or SO4?

SO2 as it results from fossil fuel combustion
