5 x 1 hour lessons

This module covers redox reactions, electrochemical cells and electrode potentials. You’ll learn to construct electrochemical cells, calculate standard electrode potentials and cell EMFs, and predict redox feasibility. These ideas underpin modern fuel cell and battery technologies.

By the end of this module you will be able to: • assign oxidation numbers and identify redox processes • construct and balance redox half-equations • describe the structure of electrochemical cells • calculate standard cell EMFs using electrode potentials • predict whether a redox reaction is feasible using E° values • use conventional notation for cells • interpret electrochemical series and trends in reactivity • explain how fuel cells and storage cells operate
