A solution of weak base is titrated to the equivalence point with a strong acid. Which one
Question:
A solution of weak base is titrated to the equivalence point with a strong acid. Which one of the following statements is most likely to be correct?
a. The pH of the solution at the equivalence point is 7.0.
b. The pH of the solution is greater than 13.0.
c. The pH of the solution is less than 2.0.
d. The pH of the solution is between 2.0 and 7.0.
e. The pH of the solution is between 7.0 and 13.0.
The reason that best supports my choosing the answer above is
a. Whenever a solution is titrated with a strong acid, the solution will be very acidic.
b. Because the solution contains a weak base and the acid (titrant) is used up at the equivalence point, the solution will be basic.
c. Because the solution contains the conjugate acid of the weak base at the equivalence point, the solution will be acidic.
