Conjugate base of Bronsted acids `H_2 O` and `HF` are

Options

A. `OH^(-)andH_(2)FH^(+)`, respectively
B. `H_(3)O^(+)andF^(-)`, respectively
C. `OH^(-)andF^(-)`, respectively
D. `H_(3)O^(+)andH_(2)F^(+)`, respectively

Answer

C

Explanation

`OH^(-)andF^(-)`, respectively
`underset("acid "1)(H_(2)O)+underset("base "1)(H_(2)O)hArrunderset("acid "2)(H_(3)O^(+))+underset("base "2)(OH^(-))`
`underset("acid "1)(HF)+underset("base "1)(H_(2)O)hArrunderset("acid "2)(H_(3)O^(+))+underset("base "2)(F^(-))`
`therefore` Conjugate bases are `OH^(-)andF^(-)` respectively
