... sulfides in air, or by treating a sulfite with an acid. It is a powerful reducing
agent, used as a bleach. It dissolves in water to form sulfurous acid (sulfuric(IV)
acid) and combines with oxygen, in the presence of a catalyst, to form sulfur(VI)
oxide.

Chemical Structure and Reactivity: An Integrated Approach
The resulting hypothetical species S(OH)4 can eliminate one water molecule to
give sulfuric(IV) acid, and then under suitable conditions another water molecule
can be lost to give SO2; this is in direct analogy to the behaviour of CCl4.
