Question

The pH at the Half-equivalence point of a weak base - strong acid tritation is:

A. Equal to pka
B. Equal to pKb
C. Less than 7.0
D. Equal to 7.0
E. Greater than 7.0

Answer 1

Less than 7

Step-by-step explanation:

during the titration of strong acid and weak base, the weak base is usually kept in the flask and strong acid is kept in the burette. So when we add strong acid slowly drop by drop, slowly the pH level of solution starts to decrease and at equivalence point the acid overpowers the base as a strong acid was taken over a weak base.
