Q. Conjugate acid of $S_{2}O_{8}^{2 -}$ is
A) $H_{2}S_{2}O_{8}$
B) $H_{2}SO_{4}$
C) $HS_{2}O_{8}^{-}$
D) $HSO_{4}^{-}$
Explanation
(c)
$Base + H^{+} \rightarrow conjugate\ acid$
$S_{2}O_{8}^{2 -} + H^{+} \rightarrow HS_{2}O_{8}^{-}$
$\therefore\ HS_{2}O_{8}^{-}$ is conjugate acid of $S_{2}O_{8}^{2 -}$.
