Acidic buffer
Question

Statement 1 : In a titration of weak monoprotic acid with strong base, the pH at the half equivalent point is pKa.

Statement 2 : At half equivalence point, it will form acidic buffer at its maximum capacity where [acid] = [salt].

Moderate
Solution

HA     +     OH-           A-       +        H2O

At the half equivalent point, [HA] = A-

    pH = pKa
