The reducing agent is a substance that causes reduction by losing electrons; therefore its oxidation state increases. The simplest way to think of this is that the oxidizing agent is the substance that is reduced, while the reducing agent is the substance that is oxidized as shown in Figure 8.2. 1 and summarized in Table 8.2. 1.A redox reaction is a reaction that involves a change in oxidation state of one or more elements. When a substance loses an electron, its oxidation state increases; thus, it is oxidized. When a substance gains an electron, its oxidation state decreases, thus being reduced. For example, for the redox reaction \[ \ce{H_2 + F_2 → 2 HF} \nonumber \]The oxygen is reduced — it gains electrons. The iron is oxidized — it loses electrons. The result of this chemical reaction is the breakdown of the metal over time. ... chemical reaction: A process that involves the rearrangement of the molecules or structure of a substance, as opposed to a change in physical form (as from a solid to a gas).Summary. Chemical reactions in which oxygen and/or hydrogen are transferred are called oxidation-reduction, or redox, reactions. Oxidation is the gain of O or loss of H. Reduction is the loss of O or gain of H. Oxidation and reduction always occur together, even though they can be written as separate chemical equations.Oxidizing Agent Definition. An oxidizing agent is a chemical substance which causes another chemical species to lose electrons. Oxidation means the loss of electrons, the loss of a hydrogen atom, or the addition of an oxygen atom. The oxidizing agent has the ability to accept or transfer those electrons.
