H_2SO_3

Explanation:

Sulfurous and sulfuric acid are both acids formed from an oxide of sulfur. Generally, in chemical lingo anyway, the suffix -ous is used to describe the acid which has one less atom of oxygen than the -ic acid.

For example, color(green)"sulphuric" acid is H_2SO_4" and color(red)"sulphurous" acid is H_2SO_3.
