Bromophenol blue is an indicator with a K_(a) value of 5.84 xx 10^(-5) . What is the percentage of this indicator in its basic form at a pH of 4.84 ?

Bromophenol blue is an indicator with a K_(a) value of 5.84 xx 10^(-5) . What is the percentage of this indicator in its basic form at a pH of 4.84 ?

An acid-base indicator has a K_(a) = 3.0 xx 10^(-5) . The acid form of the indicator is red and the basic form is blue. Then

An acid-base indicator has a K_(a) = 3.0 xx 10^(-5) . The acid form of the indicator is red and the basic form is blue. Then

An acid-base indicator has K_(a) = 3.0 xx 10^(-5) . The acid form of the indicator is red and the basic form is blue. Then:

An acid-base indicator has K_(a) = 3.0 xx 10^(-5) . The acid form of the indicator is red and the basic form is blue. Then:

An acid -base indicator has a Ka of 3.0 xx 10^(-5) The acid form of the indicator is red and the basic form is blue. Then

An acid-base indicator has a K_(a) of 3.0 xx 10^(-5) . The acid form of the indicator is red and the basic form is blue. (a) By how much must the pH change in order to change the indicator from 75% red to 75% blue?
