Sulphurous acid ,sulphuric , carbonic & nitric acid
The rain reminds me that there`s always something up there. Then i smile.
Sulphur dioxide (SO2) reacts with oxygen in the air to form sulphurous acid (H2SO3). This reaction occurs when SO2 dissolves in water, creating a weak acid known as sulphurous acid. Sulphurous acid is commonly found in the atmosphere as a result of industrial processes and volcanic emissions.
Acids in rain water: Sulphuric acid Nitric acid Sulphurous acid Nitrous acid
when gases like SO2, NO2, etc (effluents from the vehicles) are released into the atmosphere the combine with water vapour in the air to form mild acids of sulphuric and sulphurous acid, and nitric acid, etc. These when pour upon the earth fall down as acid rain.
Sulphurous acid is not a reaction (chemical or physical); the sulphurous acid (H2SO3) is a chemical compound.
Sulphurous acid (H2SO3) is a liquid at room temperature and normal air pressure.
H2SO3 is the chemical formula for sulphurous acid.
In water SO2 reacts to form H2SO3 which is sulfurous acid.
Rain is naturally somewhat acidic (pH 5.5) due to carbon dioxide dissolved in the water. Problem acid rain also has dissolved sulphur dioxide and nitrogen oxides which form sulphurous and nitrous acids.
Sulphur dioxide is an intermediate towards producing Sulphurous acid. It is a chemical compound produced by volcanoes, burning coal and petrol, such fumes passing into the air produce acid rain thus are a cause for being an environmental concern.
