#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#.
