Question

1. in the spaces provided, list any eight of the eleven factors that must be considered when choosing an electrode:

Explanation:

The following are key factors evaluated when selecting an electrode, chosen from standard considerations in electrochemistry/engineering:

1. Electrical conductivity: Ensures efficient current flow.
2. Corrosion resistance: Prevents degradation in the electrolyte.
3. Cost: Balances performance with budget constraints.
4. Mechanical strength: Withstands installation/operational stress.
5. Compatibility with electrolyte: Avoids unwanted chemical reactions.
6. Overpotential characteristics: Minimizes energy loss for reactions.
7. Long-term stability: Maintains performance over time.
8. Availability: Ensures consistent supply for scaling.

Answer:

1. Electrical conductivity
2. Corrosion resistance
3. Cost of the electrode material
4. Mechanical strength and durability
5. Compatibility with the electrolyte
6. Overpotential for target reactions
7. Long-term operational stability
8. Availability of the material
