2. Which of the following statements are true about a strong base and a weak base at a pH of 11?

HCl will not bring the pH of either solution to pH 7.

Both bases require the same amount of HCl to reach pH 7 because they are both
at the same initial pH.

The weak base will require less HCl to bring the pH to 7 than the strong base. The strong base will require less HCl to bring the pH to 7 than the weak base.

The answer is "The weak base will require less HCl to bring the pH to 7 than the strong base." Using titration curves, both bases will require the same amount of HCl to reach equivalence point but they will have different pH values. A strong acid like HCl will react with a strong base to form a solution with pH equal to 7 while HCl will react with a weak base to form a solution with pH less than 7. Hence, the weak base will require lesser HCl to bring the pH to 7.
