Oxidation is the gain of oxygen (O) while reduction is the loss of oxygen (O). Oxidation is the loss of hydrogen (H) while reduction is the gain of hydrogen (H). Oxidation and reduction reactions must occur together. The reactant oxidized is the reducing agent. The reactant reduced is the oxidizing agent.When a reactant loses electrons during a reaction, it is called oxidation. When a reactant accumulates electrons during a reaction, it is called reduction. When metals react with acid, this is a common occurrence. A reduction-oxidation or redox reaction is a type of chemical reaction in which reduction and oxidation occur at the same time.
