5 x 1 hour lessons

This module brings together redox chemistry and electrochemistry. You’ll start by reviewing oxidation numbers and redox reactions, including how to balance redox equations using half-equations in both acidic and alkaline conditions.

The second half of the module introduces electrode potentials. You'll learn how to set up electrochemical cells, measure standard electrode potentials, and use them to predict the direction of redox reactions. You'll also interpret electrochemical series data and calculate standard cell potentials, as well as explain how fuel cells work and why they are of industrial interest.

​

By the end of this module, you’ll be able to:

• Assign oxidation numbers and balance redox equations in acid and alkali

• Understand how electrochemical cells work and how to set them up

• Use standard electrode potentials to predict the feasibility of reactions

• Calculate standard cell potentials from electrode data

• Interpret electrochemical series and explain trends

• Describe the operation and advantages of hydrogen and other fuel cells
