Which of the following statements is true concerning the titration of a weak base by a solution of hydrochloric acid?
A)The solution is basic at the equivalence point.
B)The solution is acidic at the equivalence point.
C)At the equivalence point,the pH is determined by the hydrolysis of chloride ion.
D)At the equivalence point,the pH is 7.
E)At the equivalence point,there is excess hydrochloric acid.

Question

Quizplus · Accepted Answer

During the titration of a weak base with hydrochloric acid, the H+ ions from the acid react with the weak base to form the conjugate acid of the weak base. At the equivalence point, all the weak base has been neutralized, and the solution contains only the conjugate acid of the weak base and chloride ions. The conjugate acid is a weak acid, so the solution is acidic at the equivalence point.
