Answer #1

Here PbO2 -> Pb2+, in this chemical reaction PbO2 were Pb in +4 oxidation state then it converted to Pb2+ +2 oxidation state. Here a decrease of oxidation state occurs, this means gaining of electron, reduction is occurred. So here we need to calculate the standard reduction potential of the process. The standard reduction potential is the tendency for a chemical species to be reduced, at 1 atm, solution at 1M, temperature at 298K (25oC). All cell potentials are compared to hydrogen, the standard reduction potential at 25oC
