Hin is an acidic indicator (K_(Ind) =10^(-7)) which dissociates into aqueous acidic solution of 30mL of 0.05M H_(3)PO_(4) (K_(1) = 10^(-3), K_(2) = 10^(-7), K_(3) = 10^(-13)) If Hin and Ind^(Theta) posses colour P and Q , respectively, and concentration of HIn is 120 times than that of Ind^(Theta) . colour Q predominates over P when concnetration of Ind^(Theta) is 127 times of HIn . What is the pH range of the indicator.

The human eye is sensitive to colour differences of indicator only when the ratio [In^(-) ] // [Hin] is greater then 10 (or) smaller than 0.1. What should be the minimum change in the pH of solution of observe a complete colour change . (pK_(In) =5) .
