1.	Dissociation of an indicator can be considered as Hin hArr H^(+) + In ^(-)Colours of Hin and In^(-)ae differect. Which statement is correct ?
Answer» Solution ASSUMES colour of Hin when`p ^(K_(In) )+ 1` Solution assumes colour of `In^(-)` When PH =` p ^(K_(In) )-1` Solution assumes colour Hin when pH =` p ^(K_(In)) +1` Solution assumes colour of `In^(-)` whenpH =` p ^(K_(In)) -1` Solution :When `pH GT PK_(In)+1, " colour "` of ` In^(-) ` When `pH lt PK_(In) - 1 , `Colour of Hin
