It is well known that the lower value of pH has a high concentration of hydrogen ions [H+]. The lower value of the pKa shows the stronger the acid and has the greater ability to donate protons [H+]. The conclusion is that, Suppose that, HA = H+ + A- pH = pKa [HA] = [A-] pH > pKa [HA] < [A-] pH < pKa [HA] > [A-] It means a higher value of pKa shows a higher value of pH.In the question, the highest value of pKa (11.89) is of 0.1 M HA. Therefore, it shows the highest pH than the others. Answer: 0.1 M HA, pKa = 11.89
