WebAmong the drugs diazepam (weak base, pKa 3.3), oxacillin (weak base, pKa 2.8) and phenol (weak acid, pKa 9.9), which drug will be most highly ionized at a pH of 7.4? A: … WebPhenolphtalein Solution The correct answer is C. In the titration of a weak acid with a strong base, the conjugate base of the weak acid will make the pH at the equivalence point greater than 7. Therefore, you would want an indicator to change in that pH range.
