The rapid change of pH near the stoichio...

The rapid change of `pH` near the stoichiometric point of an acid-base titration is the basic of indicator detection. `pH` of the solution is related to the ratio of the concentration of conjugate acid `(Hin)` and base `(In^(-))` forms of the indicator by the expression

A

`"log"[In^(-)]/([HIn])=pK(In) – pH`

B

) `"log"[HIn]/([ In^(-)])=pK(In) – pH`

C

`"log"[HIn]/([ In^(-)])= pH – pK(In)`

D

`"log"[HIn]/([ In^(-)])= pH – pK(In)`

Text Solution

Verified by Experts

The correct Answer is:
D
`pH=pK_(In) + "log"([In^(-)])/([HIn])`
