Question

The diagram shows a Zn/MnO2-KOH alkaline dry cell.
In your response, do the following:
- Label all parts.
- Label the cathode and the anode, including the charges on each.
- Show the flow of electrons.
- Explain how the cell works. Include the oxidation and reduction half-reactions in your explanation.
Answer:

Answer 1

The zinc electrode is called the anode, the electrode at which oxidation takes place, and is labeled with a “–” sign. The copper electrode is called the cathode, the electrode at which reduction takes place, and is labeled with a “+” sign. This cell will produce a little over one volt.
