- 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.arrow_forwardWhich statements about acid-base equilibria is/are Wrong? I. The pKa = log Ka. II. A strong acid has a negative pKa value. II. A stronger acid has a pKa with a larger value than a weaker acid. IV. The stronger the base, the smaller the pKa of its conjugate acid.
