Consider two flasks. Both contain equal volumes of solution, and the molarities of the two solutions are also equal. Flask A contains a strong acid and Flask B contains a weak acid with K_a = 1 × 10^–6. Each flask is titrated with 0.10 M NaOH. Fill in the blanks in the following statements with “greater than,” “less than,” or “equal to.”

(a) Before the titrations begin, the pH in Flask A is _________ the pH in flask b. 

(b) When both titrations are halfway to the equivalence point, the pH in Flask A is _________ the pH in flask b.

(c) When both titrations are at the equivalence point, the pH in Flask A is _________ the pH in flask b.

(d) The volume of NaOH required to reach the equivalence point for Flask A is _________ the volume required to reach the equivalence point for Flask b.
