Similarly, a positive oxidation number indicates how many electr ons an atom may acquire during a chemical reaction. Note : * The chemical which gains electrons is reduced (reduces its valency) and is … In this reaction copper undergoes reduction where as iron gets oxidized. So, reduction decreases the oxidation number (valency). Lv 7. vor 10 Jahren . since both oxidation and reduction are taking place, this can be regarded as a Redox reaction the same can also be understood by using the concept of oxidation numbers. \[ \ce{VO^{2+} + H_2O \rightarrow VO_2^{+} + 2H^{+} + e^{-}}\] Each time the vanadium is oxidized (and loses another electron), its oxidation state increases by 1.
