Dissociation of an indicator can be cons...

Dissociation of an indicator can be considered as Hin `hArr H^(+) + In ^(-) ` Colours of Hin and `In^(-) ` ae differect. Which statement is correct ?

A

Solution assumes colour of Hin when `p ^(K_(In) )+ 1`

B

Solution assumes colour of `In^(-) ` When pH =` p ^(K_(In) )-1`

C

Solution assumes colour Hin when pH =` p ^(K_(In)) +1`

D

Solution assumes colour of `In^(-) ` when pH =` p ^(K_(In)) -1`

Text Solution

Verified by Experts

The correct Answer is:
C, D
When `pH gt PK_(In) +1, " colour " ` of ` In^(-) `
When `pH lt PK_(In) - 1 , ` Colour of Hin
