Determine the oxidation number of lead in each of the following oxides: PbO, PbO2, Pb2O3, Pb3O4. (b) The only known lead ions are Pb2+ and Pb4+. How can you reconcile this statement with your answer to part (A)?
Added by Amy M.
Step 1
In PbO, oxygen has an oxidation number of -2. Since there is only one oxygen atom, the oxidation number of lead (Pb) must be +2 to balance the charges. So, the oxidation number of Pb in PbO is +2. Show more…
