It forms when sulfur dioxide dissolves in water and the pure anhydrous form of sulfurous acid has never been isolated or detected. Sulfurous acid decomposes and dissociates into its chemical constituents quickly; since it is thermodynamically unstable. The decomposition reaction is,. The geometrical structure of this molecule is tetrahedral.
The geometrical structure of this molecule is trigonal pyramidal. Sulfuric Acid: Sulfuric is one of the strongest acids, and it is a diprotic acid. Sulfurous Acid: The acidity of sulfurous acid on the pH scale in equals to 1.
It is not considered as a very strong acid, but it is not a too weak acid too. Sulfuric Acid: Sulfuric acid has both oxidizing and reducing characteristic in addition to its acidic properties.
Therefore, it reacts with both metals and non-metals ; it reacts as other acids with metals producing Hydrogen gas and the relevant salt of the metal. Sulfuric acid H. Upvote 1.

Sulphurous acid is an acid having the chemical formula H 2 SO 3. It is a covalent compound containing only covalent chemical bonds. The molar mass of sulphurous acid is Sulphurous acid is a weak acid and unstable.
It is formed when sulphur dioxide SO 2 is dissolved in water. Figure 2: Chemical Structure of Sulphurous Acid. The chemical geometry of sulphurous acid is trigonal pyramidal. Although the electron geometry of the molecule is tetrahedral, the molecular geometry is trigonal pyramidal due to the presence of a lone electron pair.
Sulphurous acid cannot be isolated as the pure compound because it is formed only in the aqueous solution. Sulphurous acid aqueous solution is a reducing agent.
Sulfurous acid also acts as a bleaching agent. Sulphuric Acid: The molar mass of Sulphuric acid is Sulphurous Acid: The molar mass of Sulphurous acid is
