Question
Which of the following statements about a weak acid strong base titration is/are correct ?
Options
A.The pH after the equivalence point of the weak acid strong base titration is deter mined by using the Kb expression for the conjugate base.
B.A buffer solution of weak acid and its conjugate base is formed before the equivalence is reached.
C.The pH at the equivalence point of a weak monoprotic acid strong base titration is equal to the pH at the equivalence point of a strong acid-strong base titration.
D.The increase in pH in the region near the equivalence point of a weak acid strong base titration is grater than the pH change in the same region of a strong acid strong base titration
