A `0.1 M` solution of a weak acid HA is titrated by `NaOH` slowly. The titration curve observed is given. `ka = 4 xx 10^(-5)` at `25^(@)`C. The correct observation for the curve will be:

A

Solution will make buffer before equivalence point

B

`pH` of solution at equivalence point is `5.6`

C

`pH` of solution at equivalence point is 7

D

Salt hydrolysis cannot suitable to predict the `pH` of equivalence point

Text Solution

Verified by Experts

The correct Answer is:
A
Solution will make buffer before equation point since before equation point both `HA` amd `NaA` are present.
