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. Dissociation constant of an acidic indicator is 10^(-5) . At what p^(H) 80% of the indicator exists in molecular form ?

Correct the statement if it is wrong: Indicators show different colours in acidic and basic solutions.

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

Let the colour of the indicator (Hin colourles) will be visible only when its ionised form (pink) is 25 or more in a solution. Suppose Hln (pK_(In) = 9.0) is added to a solution of pH = 9.6. Predict what will happen. (Take log 2 = 0.3)
