Standard Reduction Potentials of Half-Cells Ionic concentrations are at 1M in water 250 C Oxidizing Agents Reducing Agents E0 Volts F2g 2e-2F-aq 287 PbO2s SO4 2-aq 4Haq 2e- PbSO 4s 2H2OA 169 MnO4-aq 8Haq 5e-Mn2aq 4H 2OA 151 Au3aq 3e-Aus 150 ClO4. Standard Reduction Potential Chart. All standard potentials are reduction potentials unless told otherwise.

Standard Reduction Potentials of Half-Cells Ionic concentrations are at 1M in water 250 C Oxidizing Agents Reducing Agents E0 Volts F2g 2e-2F-aq 287 PbO2s SO4 2-aq 4Haq 2e- PbSO 4s 2H2OA 169 MnO4-aq 8Haq 5e-Mn2aq 4H 2OA 151 Au3aq 3e-Aus 150 ClO4.

Since oxidation is the opposite of reduction the minus sign is necessary. E is the standard reduction potential. The Standard Reduction Potential Chart for chemistry classrooms lists 30 of the most useful reduction half-cell reactions are listed in descending order of reduction potential.
