Solution
Solution Steps
Step 1: Identify the Chemical Formula
The given chemical formula is $\mathrm{H}_{2} \mathrm{SO}_{3}$.
Step 2: Determine the Central Element and Its Oxidation State
The central element in $\mathrm{H}_{2} \mathrm{SO}_{3}$ is sulfur (S). The oxidation state of sulfur in $\mathrm{H}_{2} \mathrm{SO}_{3}$ is +4.
Step 3: Name the Oxyacid Based on the Oxidation State
Oxyacids of sulfur with an oxidation state of +4 are named as sulfurous acid.
