Question

Conjugate base for Bronsted acids H₂O and HF are ___________.

पर्याय

• OH^– and H₂FH⁺, respectively

• H₃O⁺ and F^–, respectively

• OH^– and F^–, respectively

• H₃O⁺ and H₂F⁺, respectively

Answer 1

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.
