Indicators

Indicators are used in chemical reactions to to signal the progress or endpoint of a reaction, changing color rapidly upon completion of the reaction. They are commonly employed in acid-base titration, redox titration, and other chemical analyses to ascertain whether the reaction has been completed.
Based on the reaction types, indicators can be divided into acid-base indicators, metal ion indicators, redox indicators, adsorption indicators, fluorescent indicators, etc.
