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. Select one: O I, II, IV O II O , IV O II, IVarrow_forward
- 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_forwardWhat is the ratio of conjugate base to undissociated acid for a weak acid with a pka of 4.4 at a pH of 9?
