At `pH=2` half of the indicator thylmol blue ( an acid type indicator)is in unionised form,find the `%` of indicator in unionised form in the solution with `[H^(+)]=4xx10^(-3)M`

The pK_("in") so an acid -type indicator is 10.5 . For which pH transition range is the indicator most suitable ?

Bromothymol blue is an indicator with a K_(a) value of 6xx10^(-5). What % of this indicator is in its basic form at a pH of 5 ?

What fraction of an indicator Hi n is the basic form at a pH of 5 if the pK_(a) of the indicator is 6 ?

% dissociation of a 0.024M solution of a weak acid HA(K_(a)=2xx10^(-3)) is :

The ionisation constant of an acid base indicator (a weak acid) is 1.0 xx 10^(-6) . The ionised form of the indicator is red and unionised form is blue. The p H change required to alter the colour of indicator from 80% red to 20% red is

What fraction of an indicator H"in" is in the basic form at a pH of 6 if pK_(a) of the indicator is 5 ?

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:

The K_a of an indicator HIn is 9 x 10^(-4) , The percentage of the basic form of indicator is 10x in a solution of pH = 4. What is x ?

An acidic indicator ionises as I_(n) H hArr "In"^(-) + H^(+) . The molecular and ions of the indicator show different colours. The indicator changed it colour if its acidic of basic form completely predominant. An indicator with P^(Kin) = 5 is added to a solution with p^(H) = 5 . What is the percentage of acidic form of the indicator

For the indicator 'HIn' the ratio (Ind^(Θ))//(HIn) is 7.0 at pH of 4.3 . What is K_(eq) for the indicator.
