Consider the following three solutions:

(i) 0.10 M solution of a weak monoprotic acid

(ii) 0.10 M solution of strong monoprotic acid

(iii) 0.10 M solution of a weak diprotic acid

Each solution is titrated with 0.15 M NaOH. Which of the following will be the same for all three solutions?

a. the volume required to reach the final equivalence point

b. the volume required to reach the first equivalence point

c. the pH at the first equivalence point

d. the pH at one-half the first equivalence point
