How does a redox indicator function
WebAn oxidation-reduction reaction between an oxidising agent and a reducing agent is known as redox titration. The chemical reaction occurs in this form of titration when electrons are transferred between reacting ions in aqueous solutions. WebOxidation/reduction (redox) indicators are colorimetric reagents which show a distinct color change at a specific electrode potential. These are all organic compounds exhibiting …
