What is the primary energy conversion that occurs in an electrochemical cell (like a battery)?

In a simple electrochemical cell made of zinc, copper, and dilute sulfuric acid, which metal acts as the anode (negative terminal)?

Define oxidation and reduction in terms of electrons.

At which electrode (anode or cathode) does oxidation occur in an electrochemical cell?

What is an electrolyte? Give an example.

Define electrolysis.

In the electrolysis of molten sodium chloride (NaCl), what product is formed at the cathode and what is formed at the anode?

When electrolyzing an aqueous solution of copper sulfate (CuSO₄) with carbon electrodes, what is observed at the negative electrode (cathode)?

Define electroplating.

In order to electroplate an iron key with silver, what should be the cathode, anode, and electrolyte?

Define corrosion. What is the specific term for the corrosion of iron?

What two substances are essential for the rusting of iron?

How does acidity affect the rate of rusting?

Explain the principle of sacrificial protection (cathodic protection) for preventing rust.

Why is a galvanized iron sheet (coated with zinc) protected from rusting even when the zinc coating is scratched?
