Solution
Conjugate base for Bronsted acids H2O and HF are OH– and F–, respectively.
Explanation:
\[\ce{\underset{acid 1}{H2O} + \underset{base 1}{H2O} ⇌ \underset{acid 2}{H3O^+} + \underset{base 2}{OH^-}}\]
\[\ce{\underset{acid 1}{HF} + \underset{base 1}{H2O} ⇌ \underset{acid 2}{H3O^+} + \underset{base 2}{F^-}}\]
∴ Conjugate bases are OH− and F− respectively.
