Equilibrium - Result Question 36
####38. Conjugate base for Brönsted acids $H_2 O$ and $HF$ are:
[2019]
(a) $OH^{-}$and $H_2 F^{+}$, respectively
(b) $H_3 O^{+}$and $F^{-}$, respectively
(c) $OH^{-}$and $F^{-}$, respectively
(d) $H_3 O^{+}$and $H_2 F^{+}$, respectively
Show Answer
Solution:
- (c) When a proton is removed from an acid, we obtain its conjugate base.
$ H_2 O \rightarrow H^{+}+OH^{-} $
$HF \rightarrow H^{+}+F^{-}$
