PPT-Reduction-oxidation (redox) couple:

pair of molecules of which one is reduced and the other is oxidized eg lactatepyruvate NADHNAD and FADH 2 FAD each pair constitutes a half reaction the reductant of one pair donates electrons and the oxidant of the other pair accepts the electrons.

Define: Give the precise meaning of a word, phrase or physical quantity.. Oxidation and Reduction. Oxidation-reduction (. redox. ) reactions involve transfer of electrons. Oxidation – loss of electrons. Reduction – gain of electrons. Both half-reactions must happen at the same time. IGCSE Chemistry . 620. OXYGEN. Gaining of oxygen is called oxidation.. Carbon + Oxygen .  Carbon dioxide. Carbon is oxidised to carbon dioxide.. Methane burns in oxygen.. CH. 4. . + . 2O. 2. . Redox. ) Reactions. Chapter 20. Salt on icy roads can make driving safer, but the salt that clings to the metallic parts of cars can cause them to corrode or rust relatively quickly. This corrosion is one example of a chemical reaction called oxidation-reduction. You will learn about oxidation-reduction reactions.. Oxidation and reduction.
