"WebThe K a of weak acids varies between 1.8×10 −16 and 55.5. Acids with a K a less than 1.8×10 −16 are weaker acids than water. If acids are polyprotic, each proton will have a unique K a. For example, H 2 CO 3 has two K a values because it has two acidic protons. The first K a refers to the first dissociation step: " - Do weak acids donate protons

WebThe better stabilised the negative charge on a conjugate base of a neutral acid is, the happier the species will be to loose a proton and thus the more acidic the proton is. All of the points you noted just emphasise that. Therefore, the only wrong assumption you are making is: more stable base = weaker acid. The correct way is: WebStrong acids and bases ionize completely in aqueous solution, while weak acids and bases ionize only partially.
