Which of the following statements about a weak acid strong base titration is//are correct?

A

The `pH` after the equivalence point of the weal acid string base titration is determined by using the `K_(b)` expression for the conjugate base.

B

A buffer solution of weal 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
