A weak base is titrated with a hydrochloric acid solution.What is the pH at the equivalence point? A)equal to pK_a B)equal to 7 C)equal to pK_b D)greater than 7 E)less than 7

Question

Quizplus · Accepted Answer

The pH at the equivalence point of a titration involving a weak base and a strong acid (like hydrochloric acid) is less than 7. This is because the salt formed in the reaction hydrolyzes in water to produce a solution that is acidic.
