$HClO_{3}$
Chlorate ion ($ClO_{3}^{-}$) has a -1 charge. Hydrogen ion ($H^{+}$) has a +1 charge. Since charges are balanced, the chemical formula will be $HClO_{3}$. When naming, -ate in chlorate ion is changed to -ic when hydrogen ions are added. Thus, the compound becomes an acid, chloric acid having the chemical formula $HClO_{3}$
