which compound does $ce{h2so4}$ represent when in an aqueous solution?
sulfur oxide
sulfuric acid
hydrogen sulfide
hydrogen disulfate

Explanation:

When the covalent compound $\text{H}_2\text{SO}_4$ is dissolved in water (aqueous solution), it is named sulfuric acid, which is the standard IUPAC name for this aqueous solution. The other options do not match: sulfur oxide refers to sulfur-oxygen compounds like $\text{SO}_2$ or $\text{SO}_3$, hydrogen sulfide is $\text{H}_2\text{S}$, and hydrogen disulfate is $\text{H}_2\text{S}_2\text{O}_7$.

Answer:

sulfuric acid
