What is the reason behind acid rain? what is the importance?

Acid rain is the result of sulfur dioxide and nitrogen oxides getting into the air after being released as pollutants from factories and vehicles. These pollutants mix with water vapor and O2 to form acid rain usually with a pH of 4.

Another way to look at it is CO2 gas reacting with water, which will create carbonic acid. This will also yield acid rain. This was simply a real life example that Dr. Lavelle mentioned to better understand acids and their properties.

By reducing the SO3 NO3 and CO3 you reduce the acid rain as those mix with H20 to create acid rain

CO2, SO2, NO2 dissolves in the water and form acidic solution, finally contributing to acid rain.

Acid rain is a byproduct of human activities. Take NO for example. Typically, atmospheric Nitrogen and Oxygen join to form NO, however, in the presence of the high temperatures of car combustion engines and electrical power stations, more spontaneous reactions occur. NO will then oxidize in the air to form NO2, which can then react with water to form nitric acid, or NO-3. This is harmful to the biodiversity of plants. Sulfuric dioxide is also produced from burning fossil fuels. When this is exposed to aerosols or specific matter, it can form SO3, which reacts with water to form HSO2-, an extremely strong acid. This demonstrates how acid rain may be produced.
