  1. Chemical indicator for redox reactionsC2formal

    A substance that changes color to indicate the endpoint of an oxidation-reduction (redox) titration, showing a change in the oxidation state of the solution.

    zh氧化还原指示剂

    • The chemist added an oxidation-reduction indicator to the solution to detect the endpoint of the titration.
    • Common oxidation-reduction indicators include diphenylamine and ferroin.
    • The color change of the oxidation-reduction indicator signaled that all the analyte had reacted.
