Question

which is the correct name for the solution hclo₃(aq)?
chloric acid
hydrochloric acid
hydrogen chlorate
hydrogen chloride trioxide

Explanation:

To name \( \text{HClO}_3(\text{aq}) \), we analyze the formula. \( \text{HClO}_3 \) is an oxyacid (contains oxygen). The anion here is \( \text{ClO}_3^- \), which is the chlorate ion. For oxyacids, when the anion ends in -ate, the acid is named with -ic acid. So \( \text{HClO}_3 \) (aq) is chloric acid. Hydrochloric acid is \( \text{HCl}(\text{aq}) \), hydrogen chlorate is not the correct acid naming, and hydrogen chloride trioxide is incorrect nomenclature.

Answer:

A. chloric acid
