A conjugate base is a substance that is formed when an acid donates a proton or $H^{+}$.

Thus, for HClO₃ :

$$\begin{gathered} HCl{O}_3 \to \mathit{C}\mathit{l}{{\mathbf{O}}_{\mathbf{3}}}^{\mathbf{-}}\mathbf{ }\mathbf{ }\mathbf{ } + H^{+} \\ \left(Acid\right) \mathbf{(}\mathit{C}\mathit{o}\mathit{n}\mathit{j}\mathit{u}\mathit{g}\mathit{a}\mathit{t}\mathit{e}\mathbf{ }\mathit{b}\mathit{a}\mathit{s}\mathit{e}\mathbf{)} \end{gathered}$$

Thus, the conjugate base of HClO₃ is ClO₃^-.

4.

A conjugate acid is a substance that is formed when a base accepts a proton or $H^{+}$.

Thus, for HSO_4^- :

$$\begin{gathered} HS{O_4}^{-} + H^{+} \to {\mathit{H}}_{\mathbf{2}}\mathit{S}{\mathit{O}}_{\mathbf{4}} \\ \left(Base\right)\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{(}\mathit{C}\mathit{o}\mathit{n}\mathit{j}\mathit{u}\mathit{g}\mathit{a}\mathit{t}\mathit{e}\mathbf{ }\mathit{a}\mathit{c}\mathit{i}\mathit{d}\mathbf{)} \end{gathered}$$

Thus, the conjugate acid of HSO_4^-  is H₂SO₄.
