Polyvinylidene fluoride (PVDF) doping enhanced the OEP of PbO 2 electrode from 1.845 V to 1.927 V in H 2 SO 4 solution [ 24 ]. To find the correct oxidation state of Pb in PbO, and each element in the compound, we use a few rules and some simple math.First, since the PbO doesn’t have an overall charge (like NO3- or H3O+) we could say that the total of the oxidation numbers for PbO will be zero since it is a neutral compound.We write the oxidation number (O.N.) This is because the net charge on the given compound is 0 and oxidation state of oxygen is considered as -2 So,x=+8/3 It shows that Pb3O4 is the combination of two compounds PbO and Pb2O3.& that's why it's oxidation state is an average of two oxidation states.
