Reason for indicator cresol red to change its color with change in pH value has to be explained. Also, color at pH 10, 8 and 6 of cresol red has to be given. Concept Introduction: Acid-base indicators are those that show property of both acid and base as their protonated forms have different colors at different pH . Indicators are generally used in titrimetric analysis. Cresol red has two transition pH ranges that are 0.2 − 1.8 and 7.2 − 8.8 . In acid, its color changes to red, and in base color becomes yellow in range 0.2 − 1.8 . For range from 7.2 − 8.8 in acid, its color changes to yellow and in base color becomes red.
