${H}_{2} S {O}_{3}$

#### 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, $\textcolor{g r e e n}{\text{sulphuric}}$ acid is H_2SO_4"# and $\textcolor{red}{\text{sulphurous}}$ acid is ${H}_{2} S {O}_{3}$.
