1, Zn Air batteries have the advantages of high energy density, low cost and are environmentally benign. The redox reaction for Zn air batteries is 2Zn + O2 â2Zn0. The electrolyte is 9 M KOH. Please write the cathode and anode half reactions, identify cathode and anode, find cathode and anode standard potential, calculate the half reaction potential at 9 M KOH electrolyte (using Nernst equation), calculate Zn Air cell voltage, identify which material is reduced, which one is oxidized.
