An acidic indicator ionises asI_(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. What is the percentage of basic form acidic indicator (p^(ka) = 6) is an aqeous NaCl solution at 25^(@) C

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
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 %`
