Write balanced chemical equations for the formation of acid rain.

Sulfuric acid (H2SO4), nitric acid (HNO3), and carbonic acid (H2CO3) are the major components of acid rain.

Sulphur dioxide + water → sulphurous acid + hydrogen

SO2 + 3H2O → H2SO4 + 2H2

Sulphur trioxide + water → sulphuric acid

SO3 + H2O → H2SO4

Nitrogen dioxide + water → nitric acid + hydrogen

2N2O + H2O→ 2HNO3 + H2

As the carbonic acid , formed by CO2 is a very weak acid , and the composition of CO2

In the air is only approximately 0.03% , its effect on our environmental is negligible . it is

Only the man-made compounds of SO2 and NO2 are the main culprits for acid rain .

Chemical equations for the formation of acid rain are

SO3 + H2O → H2SO4

2N2O + H2O→ 2HNO3 + H2
