WebHydrofluoric acid is a weak acid due to the strong attraction between the relatively small F-ion and solvated protons (H 3 O +), which does not allow it to dissociate completely in water. Therefore, if we obtain HF in an aqueous solution, we establish the following equilibrium with only slight dissociation (K a (HF) = 6.6x10 -4 , strongly favors reactants): WebApr 14, 2024 · The nature of the proton (either solvated or at chemically accessible sites from an acidic bond or organic acids) ... (pK a = 12.6 in MeCN) is less than that of azo-OMe, meaning that the azo-OMe is not appreciably protonated before the electron transfer event. However, upon reduction, the azo-OMe will be certainly be protonated (pK a ...
