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: WebTrifluoromethanesulfonyl azide is not commercially available.
