Question

Give a brief account of the oxoacids of sulphur.

Answer 1

1. Sulphur forms several oxoacids, such as sulphurous acid (H₂SO₃), sulphuric acid (H₂SO₄), and thiosulphuric acid (H₂S₂O₃).
2. These acids have sulphur bonded with oxygen and hydrogen atoms in different structures.
3. Sulphur shows different oxidation states in these acids, e.g., +4 in sulphurous acid and +6 in sulphuric acid.
4. Sulphuric acid is a strong acid widely used industrially, while sulphurous acid is weaker.
5. Structures of some important oxoacids of sulphur include sulphurous acid, peroxomonosulphuric acid, thiosulphuric acid, and dithionic acid.
