oxidation-reduction titration

An oxidation-reduction (redox) titration is a chemical analysis process used to determine the quantity of a substance by reacting it with a precisely known amount of another substance. This process involves the transfer of electrons, where one species loses electrons (oxidation) and another gains them (reduction).12

In a redox titration, a standard solution of a titrant is gradually added to a sample until the equivalence point is reached, meaning an exact equivalent of titrant has been added. This completion is signaled by an end point, often indicated by a color change of a special indicator that reacts to the change in oxidation state. These titrations are crucial for various chemical analyses and industrial applications.32
