What are the chemical equations for the formation of acid rain?

Question

I need to know how acid rain is formed, i'm writing an essay and cant find a clear version of the chemical equations used in the formation of acid rain.

Answer 1

H2O + CO2 = H2CO3
H2O + SO2 = H2SO3
H2O + NO2 = H2NO3

Answer 3

Sulphur dioxide + water → sulphurous acid + hydrogen
SO2 + 3H2O → H2SO3 + 2H2

Sulphur trioxide + water → sulphuric acid
SO3 + H2O → H2SO4

Nitrogen dioxide + water → Nitric acid + hydrogen
2NO2 + 2H2O → 2HNO3 + H2

As carbonic acid, formed by CO2, is a very weak acid, and the composition of CO2 in air is only approximately 0.03%, its affect on our environment is negligible. It is only the manmade compounds of SO2, SO3 and NO2 that are the main culprits for acid rain.

Answer 4

when there is lightning, there will be a reaction between N2 and O2 in the atmosphere : N2 + O2 ---> 2NO
NO will soon become NO2 in the atmosphere : 2NO + O2 --> 2NO2
NO2 react with H2O producing nitric acid HNO3 : NO2 + H2O --> HNO3 + NO

more over :

In the gas phase sulfur dioxide is oxidized by reaction with the hydroxyl radical via a termolecular reaction:

SO2 + OH· → HOSO2·

which is followed by:

HOSO2· + O2 → HO2· + SO3

In the presence of water sulfur trioxide (SO3) is converted rapidly to sulfuric acid:

SO3 + H2O → H2SO4

Nitric acid is formed by the reaction of OH with Nitrogen dioxide:

NO2 + OH· → HNO3

Chemistry in cloud droplets

When clouds are present the loss rate of SO2 is faster than can be explained by gas phase chemistry alone. This is due to reactions in the liquid water droplets

Hydrolysis

Sulfur dioxide dissolves in water and then, like carbon dioxide, hydrolyses in a series of equilibrium reactions:

SO2 (g)+ H2O ⇌ SO2·H2O
SO2·H2O ⇌ H++HSO3-
HSO3- ⇌ H++SO32-

In the gas phase sulfur dioxide is oxidized by reaction with the hydroxyl radical via an intermolecular reaction: SO2 + OH· → HOSO2· which is followed by: HOSO2· + O2 → HO2· + SO3 In the presence of water, sulfur trioxide (SO3) is converted rapidly to sulfuric acid: SO3 (g) + H2O (l) → H2SO4 (l) depending on the level of your education, it might suffice to combine the first two eqns into the simple oxidation of sulphur dioxide: 2SO2 + O2 -> 2SO3

Answer 6

The way is this:
From the combustion of hydrocarbons you get.
CO2 and SO3, carbon anhidride and sulfuric anhidride.
and.
CO2 + H2O = H2CO3 carbonic acid.
SO3 + H2O = H2SO4 sulfuric acid.
H2O is the water in the clouds, and those acids come with the rain.

Answer 7

Acid rain is formed when tri oxo sulphate react with water chemical equation SO3 + H20=H2S04

Answer 8

H20(l) + SO2(g) = H2SO3(l)

Water (Rain) plus released Sulphur Dioxide from combustion gives Sulphurous Acid (Acid Rain).

NB Acid rain is Sulphurous Acid (H2SO3) NOT Sulphuric Acid (H2SO4), which you would have in the lab.

Answer 9

Carbon dioxide + water → Carbonic acid
CO2 + H2O → H2CO3
Sulfur dioxide + water → sulfuric acid + hydrogen
SO2 + 2H2O → H2SO4 + H2
Nitrogen dioxide + water → Nitric acid + hydrogen
2NO2 + 2H2O → 2HNO3 + H2

that should be helpful i am qiute good at science

Answer 10

H20(water) in atmosphere combines with O3 (ozone) and S (sulphur) in the atmosphere and walla H2SO4 sulfuric acid. the equation is difficult to put on here but it is H2O(l) + S(g) + O3(g)=H2SO4(l). This comes down when it rains resulting in damage to all sorts of things and is generally linked to pollutants from steel plant, etc, They have implemented scrubbers in the plants towers to alleviate this somewhat. There are also other toxins formed in the same way from CO released from vehicles and burning fossil fuels.

Answer 11

The sulfur dioxide will rarely react with 2 water molecules. they will instead go through:
SO2 + H2O => H2SO3

the nitrogen dioxide reacts with water and becomes:
NO2 +H2O => 2HNO3
