According to the material, Redox titration corresponds to which general type of titration?

• A. Precipitation
• B. Acid/Base
• C. Redox
• D. Complexometric

Answer: (B)

Redox titration is identified by the chemical reaction at the endpoint being an oxidation-reduction process. In these titrations, the analyte and the titrant exchange electrons—one is oxidized and the other reduced—so the key change is in oxidation state rather than proton transfer, precipitation, or complex formation. Because the defining change is a redox (electron transfer) event, the general type of titration is redox. Endpoint detection often relies on a change in the redox state visible with certain indicators or measurable with a redox electrode, rather than a pH change or formation of a precipitate.
