it indicates wether a paticular substance is an acid or a base.
Recreation of an indicator using an acid and a base involves mixing a colorless or faintly colored acid-base indicator with an acid to make the solution acidic (and change color) and then adding a base to neutralize the acid and return the indicator to its original color. This process demonstrates the reversible nature of acid-base indicators and how they can be used to visually indicate the presence of acids or bases in a solution.
The most appropriate indicator for a strong acid/strong base titration is phenolphthalein.
For the titration of a strong acid, the indicator typically used is phenolphthalein. Phenolphthalein changes color in the pH range of 8.2 to 10, which is suitable for titrating a strong acid with a strong base to determine the equivalence point.
An indicator used to detect an acid or base is a substance that changes color in the presence of acids or bases. Examples of indicators include litmus paper, phenolphthalein, and universal indicator solution.
An indicator is a substance that changes color when exposed to an acid or base.
An acid base indicator is a chemical substance that has the ability to change color depending on the pH.

This indicator changes his color.

Phenolphtalein is used as indicator for titration in chemistry. Also as a pH indicator: pink in basic solutions and colorless in acidic solutions. Phenolphatelein can be used to check blood in forensic problems or as a component of some inks.
