Webb8 apr. 2024 · Acetic acid doesn't dissociate completely as it can be seen that the pH of an ethanoic acid solution of 1.0M concentration is 2.4. Acetic acid is a polar, protic solvent, with a dielectric constant of 6.2 in its liquid form. Acetic Acid Reactions Acetic acid undergoes nearly all carboxylic acid reactions. WebbOne way to determine the pH of a buffer is by using the Henderson–Hasselbalch equation, which is pH = pKₐ + log ( [A⁻]/ [HA]). In this equation, [HA] and [A⁻] refer to the equilibrium concentrations of the conjugate acid–base pair used to create the buffer solution. When [HA] = [A⁻], the solution pH is equal to the pKₐ of the acid.
