Which statement about the pKa value is false? The pKa value is calculated from the equilibrium constant for the dissociation of the acid. The pKa value is a measure of the strength of an acid. The pKa value of a given acid gives an indication of the strength of the conjugate base of that acid. A larger pKa value indicates a stronger acid and a weaker associated conjugate base. All of these statements are correct.
