Question

Review the equilibrium and choose the correct statement

$HCl{O}_4+H_{2}O\rightleftharpoons H_3{O}^{+}+Cl{O}_4^{-}$

• A. $HCl{O}_4$ is the conjugate acid of $H_{2}O$
• B. $H_3{O}^{+}$ is the conjugate base of $H_{2}O$
• C. $H_{2}O$ is the conjugate acid of $H_3{O}^{+}$
• D. $Cl{O}_4^{-}$ is the conjugate base of $HCl{O}_4$

Answer 1

The correct option is D

$Cl{O}_4^{-}$ is the conjugate base of $HCl{O}_4$

$HCl{O}_4+H_{2}O\rightleftharpoons H_3{O}^{+}+Cl{O}_4^{-}$

Here $HCl{O}_4$ and $Cl{O}_4^{-}$ constitute conjugate acid and base pair.
