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 completelypredominate. What is the percentage of basic form acidic indicator . (P^(ka) =6)is an aqeous NaCl soluition at 25% C

1.	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 completelypredominate. What is the percentage of basic form acidic indicator . (P^(ka) =6)is an aqeous NaCl soluition at 25% C
Answer» `90 %` `80 %` ` 60 %` ` 100 %` Solution :` 7 =6 + LOG ""( [In^(-) ])/( [HIn])rArr ([In^(-)])/([HIn])=10` ` ([In^(-) ])/( [In^(-)][HIn]) XX 100 =(10)/(10+1)xx 100 = 90 %`
