1.	PCl_(5) in solid state exists as PCl_(4)^(+) and PCl_(6)^(-) and also in some solvents it undergoes dissociation as 2PCl_(5) hArr PCl_(4)^(+) +PCl_(6)^(-) Which statement is wrong ?
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
