SO2 + H2O ==> H2SO3
Sulphurous acid is formed.
Sulfur dioxide and nitrogen dioxide combine with water to make acid rain. Nitric oxide is neutral but is rapidly oxidised to nitrogen dioxide.
Carbon dioxide.
A small amount of carbon dioxide will dissolve in water to produce carbonic acid, a weak acid.
The products of these reactions are supposed to be contaminants of the atmosphere and possible causes of respiratory diseases.
it is a dirty white solid with rotten egg smell soluble in acidic aqueous solution.
Carbonic, Sulphurous and Sulphuric acids are formed from Carbon Dioxide and Sulphur Dioxide which are produced naturally as well as from mad-made sources.
sulphur dioxide is formed from sulphur compounds when petrol is burned
Sulphur Dioxide.
Acid rain is generally formed when sulphur dioxide combines with water in the atmosphere to form sulphuric acid or when nitrogen dioxide combines with water in the atmosphere to form nitric acid. Reducing the amounts of sulphur in gasoline or reducing the likelihood of vehicles creating nitrogen compounds reduces the amount of acid rain.
an alkaline gas is formed
This is because sulphur dioxide is an acidic oxide. Acidic oxides are formed from non-metals.
S + O2 --> SO2 sulfer dioxide
Combustion is essentially oxidation, i.e. involving oxygen. sulfur bonds with oxygen as it is freed from the matrix of the coal
S + O2 = SO2 You get Sulphur Dioxide (It smells like burnt matches and is a poisonous gas). Lots of it is released by volcanoes.
The earths first atmosphere was created by the methane, carbon dioxide, sulphur oxides and water vapor that volcanoes were pumping out. Oxygen started to come in noticeable quantities once life had formed. Nitrogen is inert, so doesn't do anything.
Sulphurous acid is formed when sulphur dioxide dissolves in water. Sulphuric acid is formed when sulphur trioxide dissolves in water. Over time, sulphurous acid will oxidize to sulphuric. SO2 + H20 -> H2SO3 (sulphurous acid) SO3 + H20 -> H2SO4 (sulphuric acid)
The ocean water absorbed much of the carbon dioxide from the atmosphere.
