In (C), sodium remains in its oxidation state of +1 throughout the reaction. The oxidation half-reaction involves the addition of oxygen, loss of electron(s), or an increase in the oxidation state. Redox reactions are oxidation-reduction chemical reactions in which the reactants undergo a change in their oxidation states. As usual, oxidation and reduction occur together. Disproportionation. Practice determining oxidation states. Oxidation numbers are theoretical constructs, and have marginal physical significance. b. The hydrogen ions are said to be reduced and the reaction is a reduction reaction. (Bu Reaksiyonlardan Hangisi Bir Oksidasyon Indirgeme Reaksiyonu Değildir?) Thus, H 2 is the reducing agent in this reaction, and CuO acts as an oxidizing agent. We find examples of oxidation-reduction or redox reactions almost every time we analyze the reactions used as sources of either heat or work.
