It indicates that the solution's range is above or below of its transition value. For example the transition value of phenolphthalein is around 9.0. Hence it shows a pink colour in basic solutions (pH>9) and colourless in acidic solutions.
Why is phenolphthalein an appropriate indicator for acid base titrations?
Phenolphthalein is an appropriate indicator for acid-base titrations because it changes color in a pH range of about 8.2 to 10, which is close to the equivalence point of many acid-base reactions. This makes it easy to visually detect the endpoint of the titration when the acid and base have completely reacted.
