The chemical difference is the oxidation state of sulfur, but only this makes a great difference in the allover chemical properties:
Sulfuric acid formula is: H2SO4
Sulphuric acid = H2SO4
H2so3
The chemical equation for the reaction between sulfur dioxide and water to form sulfuric acid is: SO2 + H2O → H2SO3. The subsequent reaction of sulfurous acid (H2SO3) with water to form sulfuric acid is: H2SO3 + H2O → H2SO4.
The chemical formula for sulphurous acid is H2SO3.
Sulfuric acid formula is: H2SO4
Sulphuric acid = H2SO4
H2so3
The chemical equation for the reaction between sulfur dioxide and water to form sulfuric acid is: SO2 + H2O → H2SO3. The subsequent reaction of sulfurous acid (H2SO3) with water to form sulfuric acid is: H2SO3 + H2O → H2SO4.
The chemical formula for sulphurous acid is H2SO3.
The products formed from the reaction between hydrogen iodide and sulfuric acid are hydrogen sulfate (H2SO4) and iodine (I2).
correct name of H2SO3 is hydrogen sulphite .And for H2SO4 it is hydrogen Sulphate.
H2SO4 is the chemical formula of sulphuric acid.
H2SO4 is already a strong acid.If you mean what is the conjugate base, then the answer is HSO4-
H2SO3 ( Sulphurous Acid) as ther name suggests , it is an acid. Note the spelling of the name, It is the sulphur in oxidation state (IV ; (4)) Compare to Sulphuric Acid (H2SO4), where the sulphur is in oxidation state (VI : (6)).
Sulphuric Acid is H2SO4 Sulphurous Acid is H2SO3 Oleum(fuming sulphuric acid) is H2S2O7 ( Also known as pyrosulphuric acid ; very nasty stuff).
Sulfurous acid has the chemical formula H2SO3, while sulfuric acid has the chemical formula H2SO4. Sulfurous acid can be oxidized to sulfuric acid by adding an oxidizing agent, such as hydrogen peroxide or nitric acid. This oxidation process converts the sulfur atom in sulfurous acid from a +4 oxidation state to a +6 oxidation state, resulting in the formation of sulfuric acid.
