Question

Draw the conjugate acid of $H{O}^{-}$.

Answer 1

${}^{-}OH$ is the conjugate base of $H_{2}O$ .

$\underset{Base}{\stackrel{-}{O}}-H+\underset{Acid}{\stackrel{+}{N}{H}_4}\rightleftharpoons \underset{\text{Conjugate acid}}{H_{2}O}+\underset{\text{Conjugate base}}{N{H}_3}$

$\therefore$ Conjugate acid of $\stackrel{-}{O}H$ is $H_{2}O$ (Refer to Image)
