Comparing the oxidation numbers of the same elements on both sides of the equation, we note that the oxidation number of zinc changes from "0" to "+2". Losing electrons is known as "oxidation", so zinc (or zinc atoms) is being "oxidized". How many electrons are gained or lost by manganese in the overall reaction? This problem has been solved! In the case of sulfate, sulfur will have a positive oxidation state since oxygen is more electronegative than sulfur, and oxygen is therefore, assigned a negative oxidation state. given two solutions that contain MnSO4 have a final oxidation state of +3 and +2. This is also true for elements found in nature as diatomic (two-atom) elements. So we have +2+S(-2 x 4) = 0 +2+S-8 = 0. 1) Cu + HNO3 → Cu(NO3)2 … Therefore, by using the ion-electron method we can balance the Oxidation-Reduction reaction.
