Conjugate base of Bronsted acids H_2 O and HF are

Answer»

`OH^(-)andH_(2)FH^(+)`, respectively
`H_(3)O^(+)ANDF^(-)`, respectively
`OH^(-)andF^(-)`, respectively
`H_(3)O^(+)andH_(2)F^(+)`, respectively

Solution :`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
