A base type indicator `B` differs in colour from its conjugate acid.`(BH^(+))` .Acidic form is red in colour while basic form is blue in colour. Human

`:.pOH=pK_(eq)+log((["Acidic form"])/(["Baic form"]))=pK_(eq)+log((["Red"])/([Blue]))` `(pOH)_(blue)=pK_(eq)+log((b)/(a))` and `p(OH)_(red)=pK_(eq)+pK_(eq)+log((c)/(d))` so range `=pH_(blue)` to `pH_(red)=14-pK_(eq)-log((b)/(a))` to `14-pK_(eq)-log((c)/(d))`
