Consider a solution that initially contains 0.40 mol fluoride anion and 0.30 mol of hydrogen fluoride. If 0.40 mol of HCl are added to this solution, which of the following statements is FALSE? You will still have a buffer solution at the end, since you’ll still have significant amounts of both weak base and conjugate weak acid The pH will have shifted to a lower pH You’ll essentially have a weak acid solution situation, with 0.7 mol HF at the end. You will no longer have a buffer solution, since all of the weak base will have reacted with the HCl. The buffer capacity was exhausted. none of the above
