-2.71 V 6. Consider the following reduction potentials Co+ + 3e- →Co Eo =1.26 V %3D Co2+ + 2e- → Co Eo = -0.28 V When cobalt metal dissolves in 1.0 M nitric acid, will Co³+ or Co²* be the primary product (assuming standard conditions)? Explain. 7. Balance each redox reaction occurring in acidic aqueous solution. a. PbO2(s) + I (aq) → Pb2+ b. SO3²-(aq) + MnO4 (aq) – SO̟²-(aq) + Mn²+(aq) (aq) + I2(s)
