Q. Conjugate base for Bronsted acids $H_2O$ and $HF$ are:
Solution:
HF on loss of $H^{\oplus} $ ion becomes $F^{\ominus}$ is the conjugate base of HF
Example :
$\underset{\text{ Acid}}{HF } + \underset{\text{ Base}}{H_2O } \rightleftharpoons \underset{\text{ Conjugate base }}{ F^{\ominus}} + \underset{\text{ Conjugate acid}}{ H_3O^{\oplus}}$
