Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.

... 2@ 48 TO Time left 0:24:03 Consider a solution initially containing 0.40 mol fluoride anion (F) and 0.30 mol of hydrogen fluoride (HF). If 0.40 mol of HCl are added to this solution, which of the following statements is/are FALSE? Addition of 0.40 mol of HCI will lover the pH of solution by 0.4 unit. O You'll essentially have a weak acid solution situation, with 0.7 mol HF at the end. O 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. You will no longer have a buffer solution, since all of the buffer capacity was exhausted. The pH will have shifted to a lower pH.
