The indicator changed it colour if its acidic of basic form completely predominant. What is the percentage of basic form acidic indicator (p^(ka) = 6) is an aqeous NaCl solution at 25^(@) C

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
