Hauv cov tshuaj tiv thaiv redox, cov khoom uas tau txais electrons yog hu ua oxidizing tus neeg sawv cev, thiab cov khoom uas poob electrons yog hu ua tus neeg sawv cev txo. Hauv kev txiav txim siab nqaim, tus neeg sawv cev oxidizing tuaj yeem xa mus rau ib yam khoom uas tuaj yeem muab cov pa oxygen rau lwm yam khoom; Ib yam li ntawd, fluorinating tus neeg sawv cev yog ib yam khoom uas muaj peev xwm muab fluorine rau ib yam khoom, xws li chlorinating agents, brominating agents, thiab lwm yam.
Tus neeg sawv cev oxidizing yog ib yam khoom uas tau txais electrons thiab txo qis hauv cov tshuaj tiv thaiv redox. Nws lub zog oxidizing yog txiav txim siab los ntawm cov hluav taws xob- tau txais kev nyiam ntawm qhov siab dua -valence element thiab tuaj yeem ntsuas los ntawm tus qauv hydrogen electrode muaj peev xwm. Cov pa oxygen- muaj cov oxidizing cov neeg ua haujlwm ntau dua nyob rau hauv cov kua qaub vim tias X-O daim ntawv cog lus tsis ruaj khov, thaum cov khoom uas muaj ntau dua molecular symmetry (xws li perchlorate ions) muaj zog oxidizing zog. Raws li lawv cov hluav taws xob- tau txais peev xwm, lawv tuaj yeem muab faib ua peb pawg: muaj zog, nruab nrab, thiab tsis muaj zog, nrog cov pa oxygen (tus qauv muaj peev xwm 1.229V) thiab hlau ions (0.771V) ua cov kab sib faib. Raws li cov tshuaj muaj pes tsawg leeg, lawv muab faib ua inorganic thiab organic oxidizing agents, thiab raws li cov tshuaj tiv thaiv nruab nrab, lawv muab faib ua acidic (xws li sodium dichromate), yooj yim (xws li sodium hypochlorite), thiab nruab nrab (xws li iodine). Nws yog dav siv hauv metallurgical purification thiab roj teeb tsim. Thaum khaws cia, nws yuav tsum tau khaws cia kom deb ntawm cov organic teeb meem thiab acids kom tsis txhob decomposition los ntawm tshav kub los yog noo noo.
