An indicator may be selected for an acid-base application based on the pH range where the indicator changes color. A chemist wanted an indicator to change color between pH 5.8

and 6.1.The following compounds were available for selection: indicator A: Ką. A = 1.5X10¬³, indicator B:Ka. B = 1.3X10-6, indicator C: Ka. C = 1.0x10-8, and indicator D: Ka. D = 1.8X10¯8. Which would be the proper indiçator to şelect? a indicator b indicator c indicator C d. indicator
