Differences between primary and secondary cells, with examples.
Batteries are essentially commercial galvanic cells that convert the chemical energy of a spontaneous redox reaction into electrical energy. For practical use, they must be reasonably compact and provide a steady voltage.
Principles of fuel cells using the H2-O2 cell as an example.
Traditional thermal power plants are only about 40% efficient and produce heavy pollution. Fuel cells are galvanic cells designed to convert the chemical energy of combusting fuels (like hydrogen, methane, or methanol) directly into electrical energy, achieving up to 70% efficiency.
Mechanism of rusting of iron.
Corrosion (such as the rusting of iron or tarnishing of silver) is essentially an electrochemical phenomenon. A metal is oxidized by losing electrons to oxygen in the environment, forming metal oxides.
Explain how rusting is an electrochemical cell.
Focus on: identifying the specific anodic and cathodic reactions that occur on the iron surface.
