Question

Why is pH at the equivalence point larger than 7 when you titrate a weak acid with a strong base?

a. There is excess strong base at the equivalence point.

b. The conjugate base that is formed at the equivalence point reacts with water.

c. The conjugate base that is formed at the equivalence point is a strong base

d. This statement is false: the pH is always 7 at an equivalence point in a pH titration.

e. There is excess weak acid at the equivalence point.
