The following curve shows the change of `pH` during the course of titration of weak acid `HA` with a strong base. At which point in the titration curve is the concentration of acid equal to that of its conjugate base.

A

Point D

B

Point E

C

Point C

D

Point B

Verified by Experts

The correct Answer is:

D

Point B represents exactly half neutralisation of acid. At this point concentration acid left and its conjugate base are equal.
