Oxidation refers to the loss of electrons; in this process the oxidized substance releases energy. Reduction refers to the gain of electrons; in this process, the reduced substance gains energy. Oxidation-reduction reactions do not always parallel; when one substance is oxidized, another also can be oxidized at the same time.arrow_forward
