Episode 9 — Electrochemical Reactions

Galvanic Cells 1

Learners will be able to:

• Identify the species in an electrochemical reaction and distinguish between cations and anions. • Explain how redox reactions occur in aqueous solutions using reduction and oxidation reactions. • Use the table of standard electrode potential to determine the strongest oxidizing agent and reducing agent in a given reaction. • Write out half-reactions for a redox reaction, including balancing electrons and combining them into a net ionic reaction. • Describe how a galvanic cell is constructed and explain its function, including the role of the salt bridge.
