Oxidation/Reduction Reactions Reactions in which electrons are transferred from one reactant to another. Example I-1 Cu2+ + Zn (s) Cu (s) + Zn2+ Cu2+ has undergone reduction and is reduced. Oxidizing reagent: Cu2+. Reducing agent: Zn. Zn has undergone oxidation and is oxidized. . | Chapter 14 Fundamentals of Electrochemistry Chapter 15 Electrodes and Potentiometry Chapter 16 Redox Titration I. Oxidation Reduction Reactions Reactions in which electrons are transferred from one reactant to another. Example I-1 Cu2 Zn s Cu s Zn2 Oxidizing reagent Cu2 . Cu2 has undergone reduction and is reduced. Reducing agent Zn. Zn has undergone oxidation and is oxidized. Oxidizing reagent J A reagent which tends to remove electrons from another reactant. J Its oxidation number becomes less positive after it reacts. In the above reactant Cu2 is the oxidizing agent. It has undergone reduction. I_ 2e Cu2 Zn s Cu s Zn2 .
