Sulfur dioxide acts as an oxidising agen...

Sulfur dioxide acts as an oxidising agent as well as a reducing agent. Give one reaction each to show its oxidising nature and its reducing nature.

Text Solution

Verified by Experts

The structural formula of sulphur dioxide is `SO_(2)`, and it’s a covalent planar molecule which is V-shaped with an angle of 120 degrees.
Sulphur dioxide as oxidising agent : (Hydrogen sulphide)
Claus Process :
`{:(SO_(2),+,2H_(2)S,rarr,3S,+,2H_(2)O),("Sulphur",,,,"elemental",,"water"),("dioxide",,,,"sulphur",,):}`
Sulphur dioxide as reducing agent :
`SO_(2)+Cl_(2)rarrunderset("sulphuryl chloride")(SO_(2)Cl_(2))`
