Episode 11 — Electrochemical Reactions

Other Uses for Electrolysis

Learners will be able to:

• Identify the products formed during electrolysis of copper 2 chloride. • Explain why carbon rods are used in an electrochemical cell. • Calculate the voltage required for a non-spontaneous reaction, such as the electrolysis of copper 2 chloride. • Describe how silver metal is deposited on a negatively charged spoon using electrolysis. • Apply the principles of oxidation and reduction to explain the purification of impure copper.
