A zinc air battery is used to power electric vehicles, the battery uses water and oxygen gas form the air, a solid zinc electrode, a platinum electrode and an electrolyte.
1. Calculate Eo cell
2. Replacing the zinc electrode with aluminium or tin, what is 1 qualitative advantage or disadvantage for each new metal.
3. If you stayed with zinc and platinum electrodes what oxidizing agent would be need to generate at least 2.25 volts? Write out the OA's half reaction and determine the Eo cell.
4. If you drove the vehicle for 1.5 hours, what mass of oxygen from the air would be needed to produce a current of 1.9 × 10^3 A (current needed to go 110 km/hr)
