You can find examples of usage on the Divide the redox reaction into two half-reactions page. Oxygen almost always has an oxidation number of -2, except in peroxides (H. Hydrogen has an oxidation number of +1 when combined with non-metals, but it has an oxidation number of -1 when combined with metals. The algebraic sum of the oxidation numbers of elements in a compound is zero. Then, for the compound to be neutral, the oxidation numbers of all atoms should add up to zero. H2O2 + PbS --> PbSO4 + H2O. Check to see if the oxidation numbers show oxidation or reduction. The SO4 has the same oxidation numbers as in PbSO4 above.In working out oxidation numbers we assume that certain elements have fixed numbers O is -2, Cl is -1, H is +1 and alkali metals like sodium and potassium are +1. The oxidation state of any chemically bonded carbon may be assigned by adding -1 for each more electropositive atom (H, Na, Ca, B) and +1 for each more electronegative atom (O, Cl, N, P), and 0 for each carbon atom bonded directly to the carbon of interest. 1 Oxidation-Reduction Chemistry Chem 36 Spring 2002 2 Definitions nRedox reactions involve electron transfer: Cu (s) + 2 Ag+ (aq) fi Cu2+ (aq) + 2 Ag (s) Lose e-= Oxidation Gain e-= Reduction Question: Study The Following Reaction: PbO2 + 4H+ + SO42- +2e - PbSO4 +2H20 How Does The Oxidation Number For Lead (Pb) Change?
