Chemical Reactions : Oxidation-Reduction Reactions Quiz
Oxidation-Reduction reactions (also called “redox” reactions) are reactions that involve a shift of electrons between reactants. Oxidation is complete or partial loss of electrons or gain of oxygen. The loss of electrons results in an increase in charge or oxidation state. Reduction is complete or partial gain of electrons or loss of oxygen. The gain of electrons results in a decrease in charge or oxidation state. The substance in a redox reaction that loses electrons is called the reducing agent. The substance that gains electrons is called the oxidizing agent.
