14. Imagine that we are titrating a weak acid with a strong base, using thymol blue as the indicator. A very sharp endpoint is observed, with thymol blue changing completely from yellow to blue within the addition of one or two drops of base.

What is the probable pH of the equivalence point of this titration?
a) 7.0
b) 8.0
c) 8.8
d) 9.6
e) pH cannot be determined
