4. Silver oxide is used in "button batteries to power electric watches and other trinkets. These batteries generate a potential of 1.55 V and consist of a Zn anode and a Ag20 cathode immersed in a concentrated solution of KOH. The cathode reaction is based on the reduction of Ag20 to Ag metal. At the anode, Zn is oxidized to solid Zn(OH)2. Write the net ionic balanced electrochemical cell reaction and calculate the value...

The standard cell potential (Eocell) of the zinc-air battery is 1.65V. If at 25.0oC the partial pressure of oxygen in the air diffusing its cathode is 0.24 atm, what is the cell potential (Ecell)? Assume the cell reaction is: 2 Zn(s) + O2(g) yields 2 ZnO(s) The standard reduction potentials of the half-reactions in zinc-air batteries are: ZnO(s) +H2O(l) + 2e- yields Zn(s) + 2OH-(aq) Eored = -1.25V O2(g) + 2 H2O(l) + 4e- yields 4 OH-(aq) Eored= 0.401 Should...
