The fluoride ion, F-.
The conjugate base of HF is the fluoride ion F-
Yes, HF and F- are a conjugate acid-base pair. HF is the acid, and when it donates a proton, it forms the conjugate base, F-. Conversely, F- can accept a proton to form HF, making them a conjugate pair.
The conjugate base is the fluoride ion, F-
No, HF and KF do not form a buffer solution because a buffer contains a weak acid and its conjugate base (or a weak base and its conjugate acid). HF and KF are both strong acids, so they cannot act as a buffer system.
The conjugate acid of F- is HF (hydrofluoric acid). When F- gains a proton, it transforms into HF.
Since F- is the conjugate base to the weak acid HF, it is a weak base.
The conjugate acid of NaF is HF (hydrofluoric acid). When NaF accepts a proton, it forms HF.
The conjugate base and conjugate acid for HS04 is: Conjugate acid is H2SO4 Conjugate base is SO42
The conjugate acid of O2- is H2O2 (hydrogen peroxide). When O2- gains a proton, it forms H2O2.
The conjugate base of NH3 is NH2-, formed by removing a proton (H+) from NH3.
The conjugate base for CH3CH2COOH is CH3CH2COO-.
The conjugate base of HSO3- is SO32-.
