The alkaline battery is the most common primary nonrechargeable battery nowadays. Its anode consists of powdered zinc metal mixed with gel that is in contact with concentrated KOH solution which is why it is called alkaline battery. The cathode is a mixture of MnO2(s) and graphite. The mixture is separated from the cathode by a porous fabric. The entire battery is placed in a sealed steel container to reduce concentrated KOH leakage. The cathode reaction is: 2MNO2(s) + 2H2O ) + 2e- 2MNO (OH(s) + 20H-(aq) Write the anode half-reaction.Determine the overall cell reaction. If the cell potential is 1.55 V at room temperature, what is the cathode reduction half- potential?
