Question

Conjugate base for Bronsted acids $H_{2}O$ and $HF$ are :

• A. $O{H}^{-}$ and $H_2{F}^{+}$, respectively
• B. $H_3{O}^{+}$ and $F^{-}$, respectively
• C. $O{H}^{-}$ and $F^{-}$, respectively
• D. $H_3{O}^{+}$ and $H_2{F}^{+}$, respectively

Answer 1

The correct option is C $O{H}^{-}$ and $F^{-}$, respectively

$H_{2}O$ conjugate base is $O{H}^{-}$ and conjugate acid is $H_3{O}^{+}$
For HF conjugate base is $F^{-}$ and conjugate acid is $H_2{F}^{+}$
