Percent of acid present in acid rain

What is acid rain?

Acid rain literally means acid rain water. The pH value of ordinary rainwater is less than 7.But the pH value of acid rain is between 3.5- 5.6.

 

This is because non-metallic acid oxides like SO2, NO2 and CO2 are released into the atmosphere due to various natural and man-made causes. Again HCl vapor from the HCl producing plant dissolves in the air.

 

All of these gaseous elements dissolve in rainwater during precipitation to produce H2SO4, HNO3, H2CO3 and HCl acids and fall to the ground. This is called acid rain.

When some non metallic acidic oxide such as SO2, NO2, CO2 and gaseous HCl etc are mixed with dew, snowfall and rain water, forming sulfuric acid, nitric acid, carbonic acid and hydrochloric acid, come down on the earth from atmosphere, then this phenomenon is called acid rain

What is the contribution of different acids in acid rain?

Outbreaks of acid rain have been observed in different parts of the world. One of them is America, Canada, Russia, China, India etc. However, the incidence of acid rain is much lower in India.

 

However, the percent of different acids in acid rain is not specified. The percentage of different acids in acid rain can vary from one place to another place.

 

However, by examining different samples of acid rain, an approximate percentage value of different acids in acid rain has been determined.

 

It has been experimentally found that, in the creation of acid rain, the contribution of sulfuric acid is 60-65% and that of for nitric acid is 30-35%.

The contribution of other acids (such as HCl, H₂SO₃ and HNO₂) those are responsible for acid rains is1-2%.
