Answer

\begin{matrix} Base & Conjugate \space Acid \\ F^- & HF\\ C_2H_3{O_2}^- & HC_2H_3O_2\\ S{O_3}^{2-} & HS{O_3}^-\\ ClO^- & HClO \end{matrix}

Work Step by Step

1. To find the conjugate base of an acid, just remove one proton $(H^+)$ from it. - Remove a hydrogen, and subtract one from the charge. $HC_2H_3O_2 \longrightarrow C_2H_3{O_2}^-$ $HS{O_3}^- \longrightarrow S{O_3}^{2-}$ 2. To find the conjugate acid of a base, just add one proton $(H^+)$ to it. - Add a hydrogen, and sum one to the charge. $F^- \longrightarrow HF$ $ClO^- \longrightarrow HClO$
